Digital painting is an emerging art form in which traditional painting techniques such as watercolor, oils, impasto, etc. are applied using digital tools by means of a computer, a digitizing tablet and stylus, and software. Traditional painting is painting with a physical medium as opposed to a more modern style like digital. Digital painting differs from other forms of digital art, particularly computer-generated art, in that it does not involve the computer rendering from a model.

A digital potentiometer (also called a resistive digital-to-analog converter, or informally a digipot) is a digitally-controlled electronic component that mimics the analog functions of a potentiometer. It is often used for trimming and scaling analog signals by microcontrollers.

The digital repository audit method based on risk assessment (DRAMBORA) is a methodology and associated software-based toolkit developed by Digital Curation Centre (DCC) and DigitalPreservationEurope (DPE) to support the assessment of digital preservation repositories. Documentation for the DRAMBORA toolkit is available at the Digital Curation Centre's and DigitalPreservationEurope's DRAMBORA Interactive page.The DRAMBORA toolkit is intended to facilitate internal audit of digital preservation repositories by providing repository administrators with a means to assess their capabilities, identify their weaknesses, and recognise their strengths. The development of the toolkit follows a concentrated period of repository pilot audits undertaken by the DCC, conducted at a diverse range of organisations including national libraries, scientific data centres and cultural and heritage data archives. The construction of a toolkit of this kind is a dynamic process and this is the second stage in this process. The DRAMBORA toolkit represents the latest development in an ongoing international effort to conceive criteria, means and methodologies for audit and certification of digital repositories. The intention throughout its development was to build upon, extend and complement existing efforts. A key requirement has been to establish a toolkit that contributes towards a single process for repository assessment. The importance of international cooperation and collaboration, and the potential dangers associated with divergence were acknowledged very early on within the DCC and DPE's work in this area.The results of the original efforts of RLG/NARA task force and the nestor working group to develop criteria for audit and certification of trustworthy digital repositories and the work that was led by the Center for Research Libraries (CRL) were foremost within the considerations throughout the development of the DRAMBORA toolkit, and in the DCC-led pilot audits that preceded it. The DCC/DPE working group has engaged with representatives of other groups to agree upon a set of principles, representing the fundamental, objective baseline criteria for preservation repositories, and these and their underlying concepts, are profoundly important within the toolkit. It is anticipated that self-audit based on DRAMBORA can be facilitated if undertaken in association with one or both of the check-lists, and vice versa. The risk-based approach assists efforts to match a repository against these lists of requirements. Only with a clear view of an organisation's business context and its implicit risks can an auditor effectively use these requirements. The toolkit contextualises these lists so they can be more effectively applied. In addition to these resources, we have also sought to incorporate and adapt ideas and concepts from an additional, diverse range of sources, including a wide range of international information standards, many with their basis in the risk management industry aiming to broaden ever further the perspectives that our international colleagues have already established.DRAMBORA is released under the Creative Commons Attribution – Non-Commercial – Share-Alike 2.0 License.

Digital painting is an emerging art form in which traditional painting techniques such as watercolor, oils, impasto, etc. are applied using digital tools by means of a computer, a digitizing tablet and stylus, and software. Traditional painting is painting with a physical medium as opposed to a more modern style like digital. Digital painting differs from other forms of digital art, particularly computer-generated art, in that it does not involve the computer rendering from a model. The artist uses painting techniques to create the digital painting directly on the computer. All digital painting programs try to mimic the use of physical media through various brushes and paint effects. Included in many programs are brushes that are digitally styled to represent the traditional style like oils, acrylics, pastels, charcoal, pen and even media such as airbrushing. There are also certain effects unique to each type of digital paint which portray the realistic effects of say watercolor on a digital 'watercolor' painting. In most digital painting programs, the users can create their own brush style using a combination of texture and shape. This ability is very important in bridging the gap between traditional and digital painting.Digital painting thrives mostly in production art. It is most widely used in conceptual design for film, television and video games. Digital painting software such as Corel Painter, Adobe Photoshop, ArtRage, GIMP, Krita and openCanvas give artists a similar environment to a physical painter: a canvas, painting tools, mixing palettes, and a multitude of color options. There are various types of digital painting, including impressionism, realism, and watercolor. There are both benefits and drawbacks of digital painting. While digital painting allows the artist the ease of working in an organized, mess-free environment, some argue there will always be more control for an artist holding a physical brush in their hand. Some artists believe there is something missing from digital painting, such as the character that is unique to every physically made object. Many artists post blogs and comment on the various differences between digitally created work and traditionally created artwork.

Digital permanence addresses the history and development of digital storage techniques, specifically quantifying the expected lifetime of data stored on various digital media and the factors which influence the permanence of digital data. It is often a mix of ensuring the data itself can be retained on a particular form of media and that the technology remains viable. Where possible, as well as describing expected lifetimes, factors affecting data retention will be detailed including potential technology issues.Since the inception of computers, a key concept differentiating computers from other calculating machines has been their ability to store information. Over the years, various hardware devices have been designed to store ever larger quantities of data. With the development of the Internet the quantity of information available appears to continue to grow at an ever increasing rate often characterised as an Information Explosion. As information stored on traditional media such as hand-written documents, printed books, photographic images and the likes is being replaced by digital files so our social and cultural legacy to future generations will depend more and more on the permanence of digital information.However, not all this information is worth saving for any length of time; sometimes its value can be very short-lived. Other data, such as legal contracts, literature, scientific studies, are frequently expected to last for centuries. This article describes how reliable different types of storage media are at storing data over time and factors affecting this reliability.Librarians and archivists responsible for large repositories of information take a deeper view of electronic archives.Data format Data must be stored in a format which can be meaningfully accessed now and in the future.Technology reliance If data requires a special program to view it, say, as an image, then software must also be available to both interpret the basic data file and also render it appropriately. In some cases, this might also require special hardware.Archival strategy Data must remain available in the long term.At present a growing problem is the time taken to reproduce an archive, for instance following a hardware or system upgrade. Since the sheer volume of archive data continues to grow, new hardware is always required to maintain the archive and so regular migration of data to a new system must be performed on a regular basis. The time taken to migrate data is starting to approach the frequency of system upgrade such that archive transfer will become a continuous, never-ending process.Digital rights management Maintaining digital information in an accurate and accessible format over an extended retention period also must address the requirements of the authors' digital rights.In many cases the data may include proprietary information that should not be accessible to all, but only to a defined group of users who understand or have legally agreed to only utilize the information in limited ways so as to protect the proprietary rights of the original authoring team. Maintaining this requirement over decades can be a challenge that requires processes and tools to ensure total compliance.Reproducibility Digital information must be able to be reproduced as originally intended or available.This is significant especially where the original data was produced on technology at a lower level than currently possible. For example, archivists try to maintain the distinction between listening to a gramophone record played on a gramophone as opposed to a digitally cleaned version of the same recording through a modern hi-fi system.Given that individuals' personal data also seems to be growing at an alarming rate, these archiving issues affecting professional repositories will soon be manifest in small organisations and even the home.

A digital stamp in crafting, stamping, card making and scrapbooking is a digital image printed onto paper from the user's printer. Digital stamps come in a variety of formats, including PNG, JPG, and TIFF. Digital stamps offer many advantages over traditional rubber stamps because of their ability to be flipped, resized, rotated and easily stored.In addition, digital stamps can be printed on a variety of papers and cardstocks, and when properly heat sealed can be used with a variety of coloring mediums including colored pencil, copic markers, even watercolors.There are many digital stamping companies today.A digital stamp, in mail or philately, is similar to a conventional postage stamp except it is resident on or in a computer. A digital stamp can typically be downloaded and printed onto envelopes or packages by authorized individuals.Some artistamp-issuing entities have issued "digital stamps", which have usually remained only pictures on a computer.A digital stamp can also be an encoded way of "approving" or "remarking on" a digital copy of a document. Paper/hard copies of documents continue to be popular because they can be signed/initialed/remarked on in a manner that is unique and traceable to the reviewer. A digital stamp seeks to duplicate or replace this and enable a paperless exchange of information that still manages to have a verifiable comment and review.

Digital multimedia broadcasting (DMB) is a digital radio transmission technology developed in South Korea as part of the national IT project for sending multimedia such as TV, radio and datacasting to mobile devices such as mobile phones, laptops and GPS navigation systems. This technology, sometimes known as mobile TV, should not be confused with Digital Audio Broadcasting which was developed as a research project for the European Union. dBm was developed in South Korea as the next generation digital technology to replace FM radio, but the technological foundations were laid by Prof. Dr. Gert Siegle and Dr. Hamed Amor at Robert Bosch GmbH in Germany. The world's first official mobile TV service started in South Korea in May 2005, although trials were available much earlier. It can operate via satellite (S-DMB) or terrestrial (T-DMB) transmission. DMB has also some similarities with the main competing mobile TV standard, DVB-H.

Digital phobic is an informal phrase used to describe a reluctance to become fully immersed in the digital age for being fearful of how it might negatively change or alter everyday life.The fast-paced development of the digital world in the twenty-first century has contributed to the digital divide becoming a very real problem for a segment of the population for whom a lack of education of, interest in, or access to digital devices has left them excluded from the technological world and fearful of its growing omnipresence.Digital phobic is part of a growing dictionary of digital vocabulary exploring the social impact of the technological age.

The digital negative is the collective name for methods used by photographers to create negatives on transparency film for the contact printing of alternative photographic techniques. The negatives can also be enlarged using traditional gelatin silver processes, though this is usually reserved for negatives of 4x5" or larger due to quality limitations imposed by printer technology. This set of techniques is separate from the Digital negative (DNG) file format, although this format may be used to create digital negative transparencies.

Digital subtraction angiography (DSA) is a fluoroscopy technique used in interventional radiology to clearly visualize blood vessels in a bony or dense soft tissue environment. Images are produced using contrast medium by subtracting a "pre-contrast image" or mask from subsequent images, once the contrast medium has been introduced into a structure. Hence the term "digital subtraction angiography".

Digital nervous system is a phrase, popularly associated with Bill Gates of Microsoft, used to describe a vision for how the IT infrastructure of an enterprise could be analogous to the autonomic nervous system of a biological organism. Gates made extensive use of the term in his 1999 book Business @ the Speed of Thought. The actual phrase digital nervous system may not have originated with Gates however, as it has been reported that Judith Dayhoff used the term before Gates did.Steve Ballmer attempted to explain the digital nervous system by saying the following:If you think of the human body, what does our nervous system let us do? It lets us hear, see, take input. It lets us think and analyze and plan. It lets us make decisions and communicate and take action. Every company essentially has a nervous system: companies take inputs, they think, they plan, they communicate, they take action. The question is how does the nervous system in your company operate? Is the IT infrastructure really adding value?Gates himself offered the following explanation as part of a keynote speech at Microsoft's Second Annual CEO Summit in 1998.The term 'digital nervous system' is kind of an interesting one. The analogy, of course, is to the biological nervous system where you always have the information you need. You always are alert to the most important things, and you block out the information that's not important. And companies really need to have that same kind of thing: the information that's valuable getting to the people who need to know about it.Digital nervous system has also been described as being synonymous with the term 'Zero Latency Enterprise', another phrase representing the way an enterprise uses IT systems to rapidly communicate between customers, employees and trading partners.

The Texas Instruments digital signature transponder (DST) is a cryptographically enabled radio-frequency identification (RFID) device used in a variety of wireless authentication applications. The largest deployments of the DST include the Exxon-Mobil Speedpass payment system (approximately 7 million transponders), as well as a variety of vehicle immobilizer systems used in many late model Ford, Lincoln, Mercury, Toyota, and Nissan vehicles.The DST is an unpowered "passive" transponder which uses a proprietary block cipher to implement a challenge-response authentication protocol. Each DST tag contains a quantity of non-volatile RAM, which stores a 40-bit encryption key. This key is used to encipher a 40-bit challenge issued by the reader, producing a 40-bit ciphertext, which is then truncated to produce a 24-bit response transmitted back to the reader. Verifiers (who also possess the encryption key) verify this challenge by computing the expected result and comparing it to the tag response. Transponder encryption keys are user programmable, using a simple over-the-air protocol. Once correctly programmed, transponders may be "locked" through a separate command, which prevents further changes to the internal key value. Each transponder is factory provisioned with a 24-bit serial number and 8-bit manufacturer code. These values are fixed, and cannot be altered.

A digital perm is a perm that uses hot rods with the temperature regulated by a machine with a digital display, hence the name. The process is otherwise similar to that of a traditional perm. The name "digital perm" is copyrighted by a Japanese company, Paimore Co. Hairstylists usually call it a "hot perm."A normal perm basically requires only the perm solution. A digital perm requires a (different) solution plus heat.

Digital signage is a sub-segment of electronic signage. Digital displays use technologies such as LCD, LED, projection and e-paper to display digital images, video, web pages, weather data, restaurant menus, or text. They can be found in public spaces, transportation systems, museums, stadiums, retail stores, hotels, restaurants and corporate buildings etc., to provide wayfinding, exhibitions, marketing and outdoor advertising.

In the context of digital signal processing (DSP), a digital signal is a discrete-time signal for which not only the time but also the amplitude has discrete values; in other words, its samples take on only values from a discrete set (a countable set that can be mapped one-to-one to a subset of integers). If that discrete set is finite, the discrete values can be represented with digital words of a finite width. Most commonly, these discrete values are represented as fixed-point words (either proportional to the waveform values or companded) or floating-point words.The process of analog-to-digital conversion produces a digital signal. The conversion process can be thought of as occurring in two steps:sampling, which produces a continuous-valued discrete-time signal, andquantization, which replaces each sample value by an approximation selected from a given discrete set (for example by truncating or rounding).It can be shown that for signal frequencies strictly below the Nyquist limit that the original continuous-valued continuous-time signal can be almost perfectly reconstructed, down to the (often very low) limit set by the quantisation.Common practical digital signals are represented as 8-bit (256 levels), 16-bit (65,536 levels), 24-bit (16.8 million levels) and 32-bit (4.3 billion levels). But the number of quantization levels is not necessarily limited to powers of two.

A digital pill is a pharmaceutical dosage form that contains an ingestible sensor inside of a pill. The sensor begins transmitting medical data after it is consumed. The technology that makes up the pill, as well as the data transmitted by the pill's sensor, are considered to be part of digital health. The purpose of the sensor is to determine whether the person is taking their medication or not (called "adherence").

A digital orthophoto quadrangle (DOQ) is aerial photography or satellite imagery that has been corrected so that its pixels are aligned with longitude and latitude lines, and have a narrowly defined region of coverage. This is a widely used format introduced by United States Geological Survey (USGS). The correction technique is called image rectification and is a large part of photogrammetry.DOQs produced by the USGS cover an area measuring 7.5-minutes longitude by 7.5-minutes latitude (the same area covered by a USGS 1:24,000-scale topographic map, also known as a 7.5-minute quadrangle) or 3.75-minutes by 3.75-minutes. The second format is also known as a digital orthophoto quarter quadrangle (DOQQ) because each covers one quarter of a quadrangle (four 1:12,000-scale DOQQs display the same area as one 1:24,000-scale DOQ).

Digital sociology is a sub-discipline of sociology that focuses on understanding the use of digital media as part of everyday life, and how these various technologies contribute to patterns of human behavior, social relationships and concepts of the self.In general, sociologists have been slow to take up research involving social media and to personally engage in using social media for professional practice, such as blogging and Twitter. This is despite the fact that digital devices are now central to the mediation and configuration of institutions and social relationships and therefore to the very nature of sociological inquiry and research. Indeed, digital technologies are beginning to have a major impact on university education and in other educational settings and workplaces. It is argued that academics need to engage and become familiar with their affordances, transforming themselves into 'digital scholars'.The first scholarly article to have the term 'digital sociology' in the title appeared in 2009. The author reflected on the ways in which digital technologies may influence both sociological research and teaching. In 2010, 'digital sociology' was described, by Richard Neal, in terms of bridging the growing academic focus with the increasing interest from global business through the publication of the book, Expanding Sentience: Introducing Digital Sociology for moving beyond Buzz Metrics in a World of Growing Online Socialization. It was not until 2013 that the first purely academic book tackling the subject of 'digital sociology' was published. The edited collection of review chapters addressed a range of topics, including concepts and experiences of space, community, intimacy, the role played by gender and social inequalities in people's use of digital technologies and the impact of these technologies in education, health, finance and war reporting. The first sole-authored book entitled Digital Sociology was published in 2015. The first academic conference on "Digital Sociology" was held in New York, NY in 2015.Although the term ‘digital sociology’ has not yet fully entered the cultural lexicon, sociologists have engaged in research related to the internet since its inception. These sociologists have addressed many social issues relating to online communities, cyberspace and cyber-identities. This and similar research has attracted many different names such as 'cybersociology', 'the sociology of the internet', 'the sociology of online communities', 'the sociology of social media', 'the sociology of cyberculture' or something else again.Digital sociology differs from these terms in that it is wider in its scope, addressing not only the internet or cyberculture but also the impact of the other digital media and devices that have emerged since the first decade of the twenty-first century. Since the internet has become more pervasive and linked with everyday life, references to the 'cyber' in the social sciences seems now to have been replaced by the 'digital'. 'Digital sociology' is related to other sub-disciplines such as digital humanities and digital anthropology. It is beginning to supersede and incorporate the other titles above, as well as including the newest Web 2.0 digital technologies into its purview, such as wearable technology, augmented reality, smart objects, the Internet of Things and big data.

Digital Planar Holography (DPH) is a method for designing and fabricating miniature components for integrated optics. It was invented by Vladimir Yankov and first published in 2003. The essence of the DPH technology is embedding computer designed digital holograms inside a planar waveguide. Light propagates through the plane of the hologram instead of perpendicularly, allowing for a long interaction path. Benefits of a long interaction path have long been used by volume or thick holograms.

Digital Performance is a very wide category filled with a range of productions, it is a generic performance but with an extra element of incorporating and integrating computer technologies and techniques into the production. You can incorporate multimedia into any type of performance whether it is live on a theatre stage or in the street. Anything as small as video recordings or a visual image classes the production as multimedia and therefore a digital performance. When the key role in a performance is the computer technologies rather than it being an additional role is when it is classed as a digital performance. This can be as little as projections on a screen in front of a live audience to creating and devising a performance in an online environment to using animation and sensing software’s.

Digital reference (or virtual reference) is a service by which a library reference service is conducted online, and the reference transaction is a computer-mediated communication. It is the remote, NextNextcomputer-mediated delivery of reference information provided by library professionals to users who cannot access or do not want face-to-face communication. Virtual reference service is most often an extension of a library's existing reference service program.

Digital self-defense is the use of self-defense strategies by Internet users to ensure digital security; that is to say, the protection of confidential personal electronic information. Internet security software provides initial protection by setting up a firewall, as well as scanning computers for malware, viruses, Trojan horses, worms and spyware. However information at most risk includes personal details such as birthdates, phone numbers, bank account and schooling details, sexuality, religious affiliations, email addresses and passwords. This information is often openly revealed in social networking sites leaving Internet users vulnerable to social engineering and possibly Internet crime. Mobile devices, especially those with Wi-Fi, allow this information to be shared inadvertently.Digital self-defense requires Internet users to take an active part in guarding their own personal information. Four key strategies are frequently suggested to assist that protection.

A digital print matrix is the digital state from which a print art object can be instanced with original intent.The traditional term print matrix is the physical surface from which an image is printed, woodblock, plate, stone or screen. Although these may in themselves be produced digitally they comprise a traditional (physical) matrix. A digital matrix however is a repository of material which, stored digitally, is combined by the artist’s hand and instanced with original intent; Philip George’s “fluid diary” providing an early example. Technically the digital matrix comprises stable digital storage mechanisms (which retain the data when switched off) rather than volatile random access memory. Conceptually as there is no need for this storage to be in the physical presence of the artist then online and remote storage (including the Internet) may form as a whole or in part the digital matrix.

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.Simple digital signals represent information in discrete bands of analog levels. All levels within a band of values represent the same information state.

A digital pet (also known as a virtual pet, artificial pet, or pet-raising simulation) is a type of artificial human companion. They are usually kept for companionship or enjoyment. People may keep a digital pet in lieu of a real pet.Digital pets are distinct in that they have no concrete physical form other than the hardware they run on. Interaction with virtual pets may or may not be goal oriented. If it is, then the user must keep it alive as long as possible and often help it to grow into higher forms. Keeping the pet alive and growing often requires 'feeding', grooming and playing with the pet. If the interaction is not goal oriented, the user can explore the character of the pet and enjoy the feeling of building a relationship with it.Digital pets can be "simulations of real animals, as in the Petz series" or "fantasy ones like the Tamagotchi or Digimon series'" Unlike biological simulations, the pet does not usually reproduce. They generally do not die, and they can regenerate.

Digital storytelling is a short form of digital media production that allows everyday people to share aspects of their story. The media used may include the digital equivalent of film techniques (full-motion video with sound), stills, audio only, or any of the other forms of non-physical media (material that exists only as electronic files as opposed to actual paintings or photographs on paper, sounds stored on tape or disc, movies stored on film) which individuals can use to tell a story or present an idea.

The digital root (also repeated digital sum) of a non-negative integer is the (single digit) value obtained by an iterative process of summing digits, on each iteration using the result from the previous iteration to compute a digit sum. The process continues until a single-digit number is reached.For example, the digital root of 65,536 is 7, because 6 + 5 + 5 + 3 + 6 = 25 and 2 + 5 = 7.Digital roots can be calculated with congruences in modular arithmetic rather than by adding up all the digits, a procedure that can save time in the case of very large numbers.Digital roots can be used as a sort of checksum, to check that a sum has been performed correctly. If it has, then the digital root of the sum of the given numbers will equal the digital root of the sum of the digital roots of the given numbers. This check, which involves only single-digit calculations, can catch many errors in calculation.Digital roots are used in Western numerology, but certain numbers deemed to have occult significance (such as 11 and 22) are not always completely reduced to a single digit.The number of times the digits must be summed to reach the digital sum is called a number's additive persistence; in the above example, the additive persistence of 65,536 is 2.

A digital photo frame (also called a digital media frame) is a picture frame that displays digital photos without the need of a computer or printer. The introduction of digital photo frames predates tablet computers, which can serve the same purpose in some situations; however, digital photo frames are generally designed specifically for the stationary, aesthetic display of photographs and therefore usually provide a nicer-looking frame and a power system designed for continuous use.Digital photo frames come in a variety of different shapes and sizes with a range of features. Some may even play videos as well as display photographs. Owners can choose a digital photo frame that utilizes a WiFi connection or not, comes with cloud storage, and/or USB and SD card hub.

Digital obsolescence is a situation where a digital resource is no longer readable because of its archaic format: the physical media, the reader (required to read the media), the hardware, or the software that runs on it is no longer available.A prime example of this is the BBC Domesday Project from the 1980s, although its data was eventually recovered after a significant amount of effort.

The Digital solidarity fund (DSF, also known by its French name Fonds mondial de solidarité numérique/FSN) was a fund that aimed to reduce the global Digital divide, established following talks which took place during the World Summit on the Information Society in Tunis in 2005. The foundation operated under Swiss law with its headquarters in Geneva, Switzerland.The DSF has been described as "woefully wasteful, or at least grossly mismanaged". It was dissolved in 2009.The DSF was open to voluntary funding and did not rely on governmental help to function.

In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable. It involves planning, resource allocation, and application of preservation methods and technologies, and it combines policies, strategies and actions to ensure access to reformatted and "born-digital" content, regardless of the challenges of media failure and technological change.

A digital pattern generator is a piece of electronic test equipment or software used to generate digital electronics stimuli. Digital electronics stimuli are a specific kind of electrical waveform varying between two conventional voltages that correspond to two logic states ("low state" and "high state", "0" and "1"). The main purpose of a digital pattern generator is to stimulate the inputs of a digital electronic device. For that reason, the voltage levels generated by a digital pattern generator are often compatible with digital electronics I/O standards – TTL, LVTTL, LVCMOS and LVDS, for instance.Digital pattern generators are sometimes referred to as "pulse generator" or "pulse pattern generator" which may be able to function as digital pattern generators as well. Hence, the distinction between the two types of equipment may not be clear. A digital pattern generator is a source of synchronous digital stimulus; the generated signal is interesting for testing digital electronics at logic level - this is why they are also called "logic source". A pulse generator is of purpose to generate electrical pulse of different shapes; they are mostly used for tests at an electrical or analog level. Another common name for such equipment is "digital logic source" or "logic source".Digital pattern generator can produce either repetitive, or single-shot signals in which case some kind of triggering source is required (internal or external).

A digital signal controller (DSC) is a hybrid of microcontrollers and digital signal processors (DSPs). Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language.

Digital self-defense is the use of self-defense strategies by Internet users to ensure digital security; that is to say, the protection of confidential personal electronic information. Internet security software provides initial protection by setting up a firewall, as well as scanning computers for malware, viruses, Trojan horses, worms and spyware.

A digital readout (DRO) is a numeric display, usually with an integrated keyboard and some means of numeric representation. Its integral computer reads signals generated by linear encoders or (less frequently) rotary encoders installed to track machine axes, using these measures to keep track of and display to a machine operator the workpiece position (e.g., milling machines), or tool position (lathes, grinders, etc) in space.In machine-shop terminology, the complete Digital Read Out system (consisting of a computer, axis-position encoders, and a numeric display) is referred to by the acronym DRO. Such a system is commonly fitted to machines in today's shops, especially for metal working — lathes, cylindrical grinders, milling machines, surface grinders, boring mills and other machine tools — to allow the operator to work faster and with greater accuracy. Use of DROs is not limited to manually operated machines. CNC machines can usually be switched to manual operation, and in this case a form of DRO is simulated on its control panel.

A digital orthophoto quadrangle (DOQ) is aerial photography or satellite imagery that has been corrected so that its pixels are aligned with longitude and latitude lines, and have a narrowly defined region of coverage. This is a widely used format introduced by United States Geological Survey (USGS).

A digital omnivore is a descriptive term meant to capture the indiscriminate and seamless modalities that consumers use to access the World Wide Web. This cultural meme reflects "the popularization of smartphones and the introduction of tablets and other web-enabled devices that allow consumers to access media content through several touch-points during the course of their daily digital lives." As Mobile Web users increasingly own mobile devices, cross-platform multimedia consumption will continue to re-shape the digital landscape, both in terms of the type of media content they consume and how they consume it.According to a new 2011 survey from comScore, "smartphones and tablets are driving nearly 7% of all digital traffic in the United States, with two-thirds of that growth attributed to smartphones alone." Today, half of the U.S. mobile population uses mobile media, up 19% in the past year to more than 116 million people. This growth is only expected to increase as 36.1% of Americans over the age of 13 now own a smartphone.Digital omnivores are a global phenomenon driving 5% of all non-computer device Internet traffic in August 2011. Singapore leads the way at 7.2%, while the U.S and the United Kingdom both score 6.8% and Australia and Canada complete the top five global markets with 5.3% and 4.4%, respectively. Looking deeper into the 6.8% of non-PC web-browsing done in the U.S., we find that 64.4% comes from mobile phones, 28.1% from tablets and 7.5% from other devices such as game consoles and e-readers. This means that in the U.S. about 4% of overall web browsing comes from smartphones and 1.6% from tablets. While small, these figures point to the way people are beginning to toggle between devices across various day-parts.An analysis of the way consumers in the U.S. viewed news content on different devices throughout the day demonstrates the influence devices have on the way people consume content. On a typical weekend morning digital omnivores access their news using their tablet, favor their computer during the working day and return to tablet use in the evening, peaking between the hours of 9pm and midnight. Mobile phones are used for web-browsing throughout the day when users are away from their personal computer.

Digital product design is an iterative design process to solve a functional problem with a formal solution. A digital product designer identifies a real problem, offers the best possible solution, and launch it to a market that is showing demand for that particular solution. The field is considered a subset of product design. Some digital products have both digital and physical components such as Nike+ and Fitbit, but the term is mainly used for product produced through software engineering. Since digital product design have become a mainstream in creative industry, a digital product designer often times is simply referred to as product designer in job posts.

Digital radiography is a form of X-ray imaging, where digital X-ray sensors are used instead of traditional photographic film. Advantages include time efficiency through bypassing chemical processing and the ability to digitally transfer and enhance images. Also, less radiation can be used to produce an image of similar contrast to conventional radiography.Instead of X-ray film, digital radiography uses a digital image capture device. This gives advantages of immediate image preview and availability; elimination of costly film processing steps; a wider dynamic range, which makes it more forgiving for over- and under-exposure; as well as the ability to apply special image processing techniques that enhance overall display quality of the image.

A digital storage oscilloscope (often abbreviated DSO) is an oscilloscope which stores and analyses the signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides.The input analogue signal is sampled and then converted into a digital record of the amplitude of the signal at each sample time.

Digital photograph restoration is the practice of restoring the appearance of a digital copy of a physical photograph which has been damaged by natural, man made, or environmental causes or simply affected by age or neglect.Digital photograph restoration uses a variety of image editing techniques to remove visible damage and aging effects from digital copies of physical photographs. Raster graphics editors (see list below) are typically used to repair the appearance of the digital images and add to the digital copy of the photo where pieces of the physical photograph are torn or missing. Evidence of dirt, scratches, and other signs of photographic age are removed from the digital image manually, by painting over them meticulously. Unwanted color casts are removed and the image's contrast or sharpening may be altered in an attempt to restore some of the contrast range or detail that is believed to be in the original physical image. In addition image processing techniques such as image enhancement and image restoration are also applicable for the purpose of digital photograph restoration.

Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, digital publishing or printing.Until the advent of such technology, photographs were made by exposing light sensitive photographic film and paper, which was processed in liquid chemical solutions to develop and stabilize the image. Digital photographs are typically created solely by computer-based photoelectric and mechanical techniques, without wet bath chemical processingThe first consumer digital cameras were marketed in the late 1990s. Professionals gravitated to digital slowly, and were won over when their professional work required using digital files to fulfill the demands of employers and/or clients, for faster turn-around than conventional methods would allow. Starting around 2007, digital cameras were incorporated in cell phones and in the following years, cell phone cameras became widespread, particularly due to their connectivity to social media websites and email. Since 2010, the digital point-and-shoot and DSLR formats have also seen competition from the mirrorless digital camera format, which typically provides better image quality than the point-and-shoot or cell phone formats but comes in a smaller size and shape than the typical DSLR. Many mirrorless cameras accept interchangeable lenses and have advanced features through an electronic viewfinder, which replaces the through-the-lens finder image of the SLR format.

A digital signal is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on one of a finite number of values. This contrasts with an analog signal, which represents continuous values; at any given time it represents a real number within a continuous range of values.Simple digital signals represent information in discrete bands of analog levels. All levels within a band of values represent the same information state. In most digital circuits, the signal can have two possible values; this is called a binary signal or logic signal. They are represented by two voltage bands: one near a reference value (typically termed as ground or zero volts), and the other a value near the supply voltage. These correspond to the two values "zero" and "one" (or "false" and "true") of the Boolean domain, so at any given time a binary signal represents one binary digit (bit). Because of this discretization, relatively small changes to the analog signal levels do not leave the discrete envelope, and as a result are ignored by signal state sensing circuitry. As a result, digital signals have noise immunity; electronic noise, provided it is not too great, will not affect digital circuits, whereas noise always degrades the operation of analog signals to some degree.Digital signals having more than two states are occasionally used; circuitry using such signals is called multivalued logic. For example, signals that can assume three possible states are called three-valued logic.In a digital signal, the physical quantity representing the information may be a variable electric current or voltage, the intensity, phase or polarization of an optical or other electromagnetic field, acoustic pressure, the magnetization of a magnetic storage media, etcetera. Digital signals are used in all digital electronics, notably computing equipment and data transmission.

Digital radiograph

In the context of digital signal processing (DSP), a digital signal is a discrete-time signal for which not only the time but also the amplitude has discrete values; in other words, its samples take on only values from a discrete set (a countable set that can be mapped one-to-one to a subset of integers). If that discrete set is finite, the discrete values can be represented with digital words of a finite width.

The digital sum in base b of a set of natural numbers is calculated as follows: express each of the numbers in base b, then take the sum of corresponding digits and discard all carry overs. That is, the digital sum is the same as the normal sum except that no carrying is used.For example, in decimal (base 10) arithmetic, the digital sum of 123 and 789 is 802:3 + 9 = 12, discard the 10 leaving 2.2 + 8 = 10, discard the 10 leaving 0.1 + 7 = 8, there is no carry to discard.123789---802More usually the digital sum is calculated in binary (base 2) where the result only depends upon whether there are an even or odd number of 1s in each column. This is the same function as parity or multiple exclusive ors.For example:011 (3)100 (4)101 (5)---010 (2) is the binary digital sum of 3, 4 and 5.The binary digital sum is crucial for the theory of the game of nim.The digital sum in base b is an associative and commutative operation on the natural numbers; it has 0 as neutral element and every natural number has an inverse element under this operation. The natural numbers together with the base-b digital sum thus form an abelian group; this group is isomorphic to the direct sum of a countable number of copies of Z/bZ.

Digital phenotyping is a multidisciplinary field of science, defined as the “moment-by-moment quantification of the individual-level human phenotype in situ using data from personal digital devices,” in particular smartphones. The data can be divided into two subgroups, called active data and passive data, where the former refers to data that requires active input from the users to be generated, whereas passive data, such as sensor data and phone usage patterns, are collected without requiring any active participation from the user. The term was first introduced in a paper in Nature Biotechnology by Sachin H. Jain and John Brownstein.Smartphones are well suited to digital phenotyping given their widespread adoption and ownership, the extent to which users engage with the devices, and richness of data that may be collected from them. Smartphone data can be used to study behavioral patterns, social interactions, physical mobility, gross motor activity, and speech production, among others. Smartphone ownership has been in steady rise globally over the past few years. For example, in the U.S., smartphone ownership among adults increased from 35% in 2011 to 64% in 2015, and in 2017 an estimated 95% of Americans own a cellphone of some kind and 77% own a smartphone.The use of passive data collection from smartphone devices can provide granular information relevant to psychiatric and other illness phenotypes. Types of relevant passive data include GPS data to monitor spatial location, accelerometer data to record movement and gross motor activity, and call and messaging logs to document social engagement with others.

Digital rhetoric is a way of informing, persuading, and inspiring action in an audience through digital media. It is an advancing form of communication composed, created, and distributed through multimedia platforms. Rhetoric combines multiple methods such as persuasion, effective writing, and effective speaking to present information in inventive ways. The meaning of rhetoric has changed over time, developing with changes in technologies.

Like microcontrollers, DSCs have fast interrupt responses, offer control-oriented peripherals like PWMs and watchdog timers, and are usually programmed using the C programming language, although they can be programmed using the device's native assembly language. On the DSP side, they incorporate features found on most DSPs such as single-cycle multiply–accumulate (MAC) units, barrel shifters, and large accumulators. Not all vendors have adopted the term DSC. The term was first introduced by Microchip Technology in 2002 with the launch of their 6000 series DSCs and subsequently adopted by most, but not all DSC vendors. For example, Infineon and Renesas refer to their DSCs as microcontrollers.)DSCs are used in a wide range of applications, but the majority go into motor control, power conversion, and sensor processing applications. Currently DSCs are being marketed as green technologies for their potential to reduce power consumption in electric motors and power supplies.In order of market share, the top three DSC vendors are Texas Instruments, Freescale, and Microchip Technology, according to market research firm Forward Concepts (2007). These three companies dominate the DSC market, with other vendors such as Infineon and Renesas taking a smaller slice of the pie.

Digital reference (or virtual reference) is a service by which a library reference service is conducted online, and the reference transaction is a computer-mediated communication. It is the remote, NextNextcomputer-mediated delivery of reference information provided by library professionals to users who cannot access or do not want face-to-face communication. Virtual reference service is most often an extension of a library's existing reference service program. The word "reference" in this context refers to the task of providing assistance to library users in finding information, answering questions, and otherwise fulfilling users’ information needs. Reference work often but not always involves using reference works, such as dictionaries, encyclopedias, etc. This form of reference work expands reference services from the physical reference desk to a "virtual" reference desk where the patron could be writing from home, work or a variety of other locations.The terminology surrounding virtual reference services may involve multiple terms used for the same definition. The preferred term for remotely delivered, computer-mediated reference services is "virtual reference", with the secondary non-preferred term "digital reference" having gone out of use in recent years. "Chat reference" is often used interchangeably with virtual reference, although it represents only one aspect of virtual reference. Virtual reference includes the use of both synchronous (i.e., IM, videoconferencing) and asynchronous communication (i.e., texting and email). Here, "synchronous virtual reference" refers to any real-time computer-mediated communication between patron and information professional. Asynchronous virtual reference is all computer-mediated communication that is sent and received at different times.

A digital pill is a pharmaceutical dosage form that contains an ingestible sensor inside of a pill. The sensor begins transmitting medical data after it is consumed. The technology that makes up the pill, as well as the data transmitted by the pill's sensor, are considered to be part of digital health. The purpose of the sensor is to determine whether the person is taking their medication or not (called "adherence"). There are privacy concerns with respect to who receives the data and what is done with it.The first digital pill to be approved by the United States Food and Drug Administration, a version of aripiprazole (Abilify) manufactured by Otsuka Pharmaceutical, was approved in November 2017. This digital pill's sensor is activated by acid in the stomach, and generates an electrical signal that is picked up by a patch worn on the ribcage; the patch in turn forwards information to a smartphone app. The drug is taken by people with schizophrenia. People with the condition tend to have problems with adherence, and the digital pill could help with that; however some people with schizophernia have paranoia which the digital pill could make worse.

In library and archival science, digital preservation is a formal endeavor to ensure that digital information of continuing value remains accessible and usable. It involves planning, resource allocation, and application of preservation methods and technologies, and it combines policies, strategies and actions to ensure access to reformatted and "born-digital" content, regardless of the challenges of media failure and technological change. The goal of digital preservation is the accurate rendering of authenticated content over time. The Association for Library Collections and Technical Services Preservation and Reformatting Section of the American Library Association, defined digital preservation as combination of "policies, strategies and actions that ensure access to digital content over time." According to the Harrod's Librarian Glossary, digital preservation is the method of keeping digital material alive so that they remain usable as technological advances render original hardware and software specification obsolete.

A digital public square (DPS) is a user-driven website that relies upon user-generated content (UGC), created by a group of people with a common interest in a specific community. At its most basic, a digital public square represents an evolution in how people discover, read and share news, information and content. Users/content providers share the common goal of informing and becoming more informed about a shared geographic community or a community of ideas.Modeled after the traditional “public square” where townspeople would gather to exchange views, a digital public square provides a virtual platform for the exploration of issues and the sharing of ideas, creativity and opinions while developing solutions to a community's challenges. A thriving digital public square has a rich content stream that may include video footage of community events and an interactive community record of nonprofit news and resources. The DPS offers a platform for dialogue and encourages people to connect in a virtual setting to establish relationships that can effect social change.

Digital scrapbooking is the term for the creation of a new 2D artwork by re-combining various graphic elements. It is a form of scrapbooking that is done using a personal computer, digital or scanned photos and computer graphics software. It is a relatively new form of the traditional print scrapbooking.Digital scrapbooking kits are available to purchase and download at many websites that specialize in the craft. Kits contain graphics and word-art and are usually themed and color-coordinated. They usually consist of a mix of background images and "cut out" images containing alpha channels. Once a kit has been download to the computer, it can then be used over and over again to make new scrapbook pages (scrapbook layouts) within the software program that one chooses to use, often in combination with the users's own family photographs, scanned keepsakes and other elements scanned on a flatbed scanner. Scanning is usually done at 300dpi, to make the resulting images suitable for print.Kits are sometimes licensed differently from the sort of traditional royalty-free stock of the sort that can be purchased per-item at online stock photography sites. Some kit packs will be wholly royalty-free, but some kit makers may restrict usage to non-commercial work only. Some may specifically forbid the sale of commercial greetings cards and gift tags that may be made with their kits. Licensing may vary from kit to kit, even from the same maker. Some kits include re-colored public domain material. In contrast to stock, creators of digital scrapbooking kits often require a credit or byline to indicate that their image elements have been used in a new creation.Some artistic individuals combine digital scrapbooking with traditional scrapbooking to create what's known as hybrid scrapbooking. Hybrid scrapbooking involves creating layouts on the computer using digital supplies that will then be printed and combined with traditional supplies such as buttons, ribbons and other elements.The traditional scrapbooking market appears to have declined in the USA since 2010, probably due to the recession, and digital scrapbooking (being potentially a much cheaper form of scrapbooking) may have increased accordingly.Digital Scrapbooking can also be done online by uploading photos to a scrapbooking website.

Digital phobic is an informal phrase used to describe a reluctance to become fully immersed in the digital age for being fearful of how it might negatively change or alter everyday life.The fast-paced development of the digital world in the twenty-first century has contributed to the digital divide becoming a very real problem for a segment of the population for whom a lack of education of, interest in, or access to digital devices has left them excluded from the technological world and fearful of its growing omnipresence.Digital phobic is part of a growing dictionary of digital vocabulary exploring the social impact of the technological age. The phrase considers the fears associated with technological evolution and change, and acknowledges the possibility of exclusion as a result of a rising reliance on technology in day-to-day life.

Digital Prototyping gives conceptual design, engineering, manufacturing, and sales and marketing departments the ability to virtually explore a complete product before it’s built. Industrial designers, manufacturers, and engineers use Digital Prototyping to design, iterate, optimize, validate, and visualize their products digitally throughout the product development process. Innovative digital prototypes can be created via CAutoD through intelligent and near-optimal iterations, meeting multiple design objectives (such as maximised output, energy efficiency, highest speed and cost-effectiveness), identifying multiple figures of merit, and reducing development gearing and time-to-market. Marketers also use Digital Prototyping to create photorealistic renderings and animations of products prior to manufacturing. Companies often adopt Digital Prototyping with the goal of improving communication between product development stakeholders, getting products to market faster, and facilitating product innovation.Digital Prototyping goes beyond simply creating product designs in 3D. It gives product development teams a way to assess the operation of moving parts, to determine whether or not the product will fail, and see how the various product components interact with subsystems—either pneumatic or electric. By simulating and validating the real-world performance of a product design digitally, manufacturers often can reduce the number of physical prototypes they need to create before a product can be manufactured, reducing the cost and time needed for physical prototyping. Many companies use Digital Prototyping in place of, or as a complement to, physical prototyping.Digital Prototyping changes the traditional product development cycle from design>build>test>fix to design>analyze>test>build. Instead of needing to build multiple physical prototypes and then testing them to see if they’ll work, companies can conduct testing digitally throughout the process by using Digital Prototyping, reducing the number of physical prototypes needed to validate the design. Studies show that by using Digital Prototyping to catch design problems up front, manufacturers experience fewer change orders downstream. Because the geometry in digital prototypes is highly accurate, companies can check interferences to avoid assembly issues that generate change orders in the testing and manufacturing phases of development. Companies can also perform simulations in early stages of the product development cycle, so they avoid failure modes during testing or manufacturing phases. With a Digital Prototyping approach, companies can digitally test a broader range of their product’s performance. They can also test design iterations quickly to assess whether they’re over- or under-designing components.Research from the Aberdeen Group shows that manufacturers that use Digital Prototyping build half the number of physical prototypes as the average manufacturer, get to market 58 days faster than average, and experience 48 percent lower prototyping costs.

Digital puppetry is the manipulation and performance of digitally animated 2D or 3D figures and objects in a virtual environment that are rendered in real time by computers. It is most commonly used in filmmaking and television production, but has also been used in interactive theme park attractions and live theatre.The exact definition of what is and is not digital puppetry is subject to debate among puppeteers and computer graphics designers, but it is generally agreed that digital puppetry differs from conventional computer animation in that it involves performing characters in real time, rather than animating them frame by frame.Digital puppetry is closely associated with motion capture technologies and 3D animation, as well as skeletal animation. Digital puppetry is also known as virtual puppetry, performance animation, living animation, live animation and real-time animation (although the latter also refers to animation generated by computer game engines). Machinima is another form of digital puppetry, and Machinima performers are increasingly being identified as puppeteers.

Digital poetry is a form of electronic literature, displaying a wide range of approaches to poetry, with a prominent and crucial use of computers. Digital poetry can be available in form of CD-ROM, DVD, as installations in art galleries, in certain cases also recorded as digital video or films, as digital holograms and on the World Wide Web or Internet.A significant portion of current publications of poetry are available either only online or via some combination of online and offline publication. There are many types of 'digital poetry' such as hypertext, kinetic poetry, computer generated animation, digital visual poetry, interactive poetry, code poetry, holographic poetry (holopoetry), experimental video poetry, and poetries that take advantage of the programmable nature of the computer to create works that are interactive, or use generative or combinatorial approach to create text (or one of its states), or involve sound poetry, or take advantage of things like listservs, blogs, and other forms of network communication to create communities of collaborative writing and publication (as in poetical wikis).Digital computers allow the creation of art that spans different media: text, images, sounds, and interactivity via programming. Contemporary poetries have, therefore, taken advantage of this toward the creation of works that synthesize both arts and media. Whether a work is poetry or visual art or music or programming is sometimes not clear, but we expect an intense engagement with language in poetical works.

A digital sensor is an electronic or electrochemical sensor, where data conversion and data transmission are done digitally.Sensors are often used for analytical measurements, i.e. the measurement of chemical and physical properties of liquids. Typical measured parameters are pH value, conductivity, oxygen, redox potentials and others. Such measurements are used in the industrial world and give vital input for process control. Sensors used to be of analogue type, but today more and more digital sensors are used. This article describes the difference and the reason for the development of digital sensors.

Digital sociology

Digital rhetoric is a way of informing, persuading, and inspiring action in an audience through digital media. It is an advancing form of communication composed, created, and distributed through multimedia platforms. Rhetoric combines multiple methods such as persuasion, effective writing, and effective speaking to present information in inventive ways. The meaning of rhetoric has changed over time, developing with changes in technologies. Online media are increasingly used as communication and information platforms, and since more text is placed online, there is more opportunity for persuasion through innovative and creative means. Because of this shift in rhetoric, the relationship between writers and readers has changed in form, communication style, and effectiveness. Digital rhetoric is advancing and changing how people choose to communicate their ideas with broader audiences. Both rhetoric and digital rhetoric hold various meanings and definitions depending upon who is looking at it; for example, the online journal Harlot of the Arts holds a competition through Twitter for people to define rhetoric, and the submissions are extremely varied.

A digital object memory (DOMe) is a digital storage space intended to keep permanently all related information about a concrete physical object instance that is collected during the lifespan of this object and thus forms a basic building block for the Internet of Things (IoT) by connecting digital information with physical objects.Such memories require each object instance to be uniquely identified and this ID to be attached to the physical object. The underlying techniques to create identification codes and to attach them to objects are manifold but machine-readable techniques are mandatory. Commonly used are barcodes with one or two dimensions (e.g. QRcode or DataMatrix) and radio based tags like RFID or NFC. Such codes or tags are a low cost solution but demand an underlying server infrastructure to host the memory data.

The digital root (also repeated digital sum) of a non-negative integer is the (single digit) value obtained by an iterative process of summing digits, on each iteration using the result from the previous iteration to compute a digit sum.

Digital phenotyping

A digital storage oscilloscope (often abbreviated DSO) is an oscilloscope which stores and analyses the signal digitally rather than using analog techniques. It is now the most common type of oscilloscope in use because of the advanced trigger, storage, display and measurement features which it typically provides.The input analogue signal is sampled and then converted into a digital record of the amplitude of the signal at each sample time. The sampling frequency should be not less than the Nyquist rate to avoid aliasing. These digital values are then turned back into an analogue signal for display on a cathode ray tube (CRT), or transformed as needed for the various possible types of output—liquid crystal display, chart recorder, plotter or network interface.Digital storage oscilloscope costs vary widely; bench-top self-contained instruments (complete with displays) start at US$300 or even less, with high-performance models selling for tens of thousands of dollars. Small, pocket-size models, limited in function, may retail for as little as US$50.

Digital probabilistic physics is a branch of digital philosophy which holds that the universe exists as a nondeterministic state machine. The notion of the universe existing as a state machine was first postulated by Konrad Zuse's book Rechnender Raum. Adherents hold that the universe state machine can move between more and less probable states, with the less probable states containing more information. This theory is in contrast to digital physics, which holds that the history of the universe is computable and is deterministically unfolding from initial conditions.The fundamental tenets of digital probabilistic physics were first explored at great length by Tom Stonier in a series of books which explore the notion of information as existing as a physical phenomenon of the universe. According to Stonier, the arrangement of atoms and molecules which make up physical objects contains information, and high-information objects such as DNA are low-probability physical structures. Within this framework, civilization itself is a low-probability construct maintaining its existence by propagating through communication. Stonier's work has been unique in considering information as existing as a physical phenomenon, being broader than as an application to the domain of telecommunications.To distinguish the probability of the physical state of the molecules from the probability of the energy distribution of thermodynamics, the term extropy was appropriated to define the probability of the atomic configuration, as opposed to the entropy. Thus, in thermodynamics, a 'coarse-grain' set of partitions is defined which groups together similar microscopically different states and in digital probabilistic physics the specific microscopic state probability is considered alone. The extropy is defined to be the self-information of the Markov chain describing the physical system.The extropy of a system X ( A n ) {\displaystyle X(A_{n})} in bits associated with the Markov chain configuration A n {\displaystyle A_{n}} whose outcome has probability p {\displaystyle p} is: X ( A n ) = log 2 ⁡ ( 1 p ( A n ) ) = − log 2 ⁡ ( p ( A n ) ) {\displaystyle X(A_{n})=\log _{2}\left({\frac {1}{p(A_{n})}}\right)=-\log _{2}(p(A_{n}))} Within this philosophy, the probability of the physical system does not necessarily change with the deterministic flow of energy through the atomic framework, but rather moves into a lesser probability state when the system goes through a bifurcating transition. Examples of this include Bernoulli cell formation, quantum fluctuations in a gravitational field causing gravitational precipitation points, and other systems moving through unstable self-amplifying state transitions.

A scanning back is a type of digital camera back. Digital imaging devices typically use a matrix of light-sensitive photosensors, such as CCD or CMOS technologies. These sensors can be arranged in different ways, like a Bayer filter, where each row captures RGB components, or using one full-sized layer for each color, such as the Foveon X3 sensor.A digital scan back takes a similar approach to the second type of photosensor, but instead of using one matrix for each component, it uses one array per component. This translates to a 3xN sensor matrix, where N is typically a large number (between 5,000 for earlier models and 15,000 for newer models), which is then placed vertically in a holder. To take an image, the sensor travels the x axis, taking one exposure per point.

A Digital Outcrop Model (DOM), also called a virtual outcrop model, is a digital 3D representation of the outcrop surface, mostly in a form of textured polygon mesh.DOMs allow for interpretation and reproducible measurement of different geological features, e.g. orientation of geological surfaces, width and thickness of layers. The quantity of identifiable and measurable geological features highly depends on the outcrop model resolution and accuracy.Using remote sensing techniques enables these 3D models to cover areas with difficult accessibility, e.g. several meter high cliff walls. The fact that geological interpretation can be performed on the screen, also in inaccessible areas where using conventional fieldwork methods may be unsafe, and the large quantity of data that can be collected in relatively short time are the key advantages of using DOMs. Georeferencing digital outcrop models allows for integration with other spatial data, e.g. results of digital geologic mapping or GIS.Alternatively to the photorealistic textured models 3D digital outcrop models may be represented by a point cloud coloured with the spectral (RGB) data from the corresponding images. Such surface model representation accurately describes the topography of the outcrop but due to its discrete nature is often difficult to interpret (see Figure 1.). Texturing digital polygonal outcrop models with images enhances the models with high resolution continuous data and therefore facilitates geological interpretation.

Digital Planar Holography (DPH) is a method for designing and fabricating miniature components for integrated optics. It was invented by Vladimir Yankov and first published in 2003. The essence of the DPH technology is embedding computer designed digital holograms inside a planar waveguide. Light propagates through the plane of the hologram instead of perpendicularly, allowing for a long interaction path. Benefits of a long interaction path have long been used by volume or thick holograms. Planar configuration of the hologram provider for easier access to the embedded diagram aiding in its manufacture.Light can be confined in waveguides by a refractive index gradient. Light propagates in a core layer, surrounded by a cladding layer(s), which should be selected the core refractive index Ncore is greater than that of cladding Nclad: Ncore> Nclad. Cylindrical waveguides (optical fibers) allow for one-dimensional light propagation along the axis. Planar waveguides, fabricated by sequential depositing flat layers of transparent materials with a proper refractive index gradient on a standard wafer, confine light in one direction (axis z) and permit free propagation in two others (axes x and y).Light waves propagating in the core infiltrate both cladding layers to a small degree. If the refractive index is modulated in the wave path, light of each given wavelength can be directed to the desired point.The DPH technology, or Yankov hologram, comprises design and fabrication of the holographic nano-structures inside a planar waveguide, providing light processing and control. There are many ways of modulating the core refractive index, the simplest of which is engraving the required pattern by nanolithography means. The modulation is created by embedding a digital hologram on the lower or upper core surface or on the both of them. According to NOD statement, standard lithographical processes can be used, making mass production straightforward and inexpensive. Nanoimprinting could be another viable method of fabricating DPH patterns.Each DPH pattern is customized for a given application and computer-generated. It consists of numerous nano-grooves, each about 100 nm wide, positioned in a way, providing maximum efficiency for a specific application.The devices are fabricated on standard wafers; one of typical devices is presented below (from the NOD web site). While the total number of nano-grooves is huge (≥106), a typical device size of DPH devices is on the millimeter scale. The small footprint of the DPH makes it possible to combine with other elements of photonic integrated circuits, such as coarse demultiplexers and interferometers.Nano-Optic Devices, LLC (NOD) developed the DPH technology and applied it for commercializing nano-spectrometers. There are additional numerous applications for the DPH in integrated optics.The pictures below from the NOD website demonstrate a DPH structure (left) and a nano-spectrometer hologram for the visible band (right).

All these digital electronics need data to be presented to them in a digital format (i.e. the data have to be digitally conditioned). This is called digital conditioning. Since computers are electronics devices, all the information they work with has to be digitally formatted. Therefore, if they are used to control a variable such as temperature, then the temperature has to be represented digitally. That's why we need digital signal conditioning to condition process-control signal to be an approximated digital format.

Digital obsolescence is a situation where a digital resource is no longer readable because of its archaic format: the physical media, the reader (required to read the media), the hardware, or the software that runs on it is no longer available.A prime example of this is the BBC Domesday Project from the 1980s, although its data was eventually recovered after a significant amount of effort. Cornell University Library’s digital preservation tutorial (now hosted by ICPSR) has a timeline of obsolete media formats, called the “Chamber of Horrors”, that shows how rapidly new technologies are created and cast aside.
