Digit symbol substitution test
The digit symbol substitution test (DSST) is a timed neuropsychological test of processing speed, in which a person copies geometric symbols beneath matching digits using a key.
Digital
Digital describes representing information using discrete values, most commonly the binary states 0 and 1, and labels the technology built on it, from computers to signal processing.
Digital Ally
Digital Ally, Inc. was an American company in Overland Park, Kansas, founded in 2004, that made body cameras, in-car video systems, and cloud evidence management software for law enforcement.
Digital AMPS
Digital AMPS, also known as D-AMPS, was a 2G mobile phone standard in North America, defined by IS-54 and IS-136 as the digital evolution of analog AMPS.
Digital architecture
Digital architecture is architecture designed, developed, or fabricated with substantial reliance on computer technologies, from CAD and BIM to parametric, generative, and algorithmic design, emerging as a design current in the 1990s.
Digital art
Digital art: art using digital technology as a medium, from Laposky's 1952 oscilloscope Oscillons and 1960s plotter works by Molnár and Mohr to net art, VR, and NFTs; distinct from art merely using digital tools, with unique preservation challenges.
Digital asset management
Digital asset management (DAM) is a class of enterprise software that stores, organizes, and distributes rich media, managing the metadata and usage rights attached to it.
Digital assets in estate administration

Digital Audio Broadcasting
Digital Audio Broadcasting (DAB), also known as DAB digital radio, is a digital radio standard developed in Europe's Eureka 147 program; its updated variant DAB+ is now deployed in most markets.
Digital Audio Tape
Digital Audio Tape (DAT) is a digital audio format introduced by Sony in 1987 that stores PCM sound on a small cassette and became a studio mastering standard.
Digital audio workstation
A digital audio workstation (DAW) is an electronic device or software application for recording, editing, and producing audio files, used widely in music production, podcasting, and sound design.
Digital authoritarianism
Digital authoritarianism: authoritarian regimes' use of digital technology to surveil, repress, and manipulate populations. Also called digital repression or dictatorship. Distinguished by the Chinese model of high-tech surveillance export and Russian disinformation-based variants.
Digital backpropagation
Digital backpropagation (DBP) is a digital signal processing technique in coherent optical fiber communication that compensates chromatic dispersion and Kerr nonlinearity by solving the nonlinear Schrödinger equation backward.
Digital beamforming
Digital beamforming is a signal-processing technique in which each antenna element's signal is digitized individually, then combined in a digital processor to form flexible beams with high cost.
Digital blackface
Digital blackface: non-Black people performing Blackness online via reaction GIFs, memes, AAVE, emojis, and video. Term coined by Joshua Lumpkin Green (2006), popularized by Lauren Michele Jackson; extends to TikTok and AI avatars.
Digital breast tomosynthesis
Digital breast tomosynthesis (DBT) is an X-ray technique that reconstructs low-dose breast projections into thin slices, revealing lesions hidden by overlapping tissue in 2D mammograms.
Digital camera
A digital camera, also known as a digicam or digital still camera, captures photographs electronically with an image sensor instead of film; the first was built by Steven Sasson at Kodak in 1975.
Digital China Group
Digital China Group (神州数码集团) is a Chinese information-technology company headquartered in Shenzhen, spun off from Lenovo in 2015, whose main business is IT distribution, cloud services, and own-brand Kunpeng servers.

Digital cinema
Digital cinema, also known as D-cinema, is the set of technologies used to create, distribute, and project movies in theaters digitally, replacing 35 mm film prints.
Digital Cinema Package
Digital Cinema Package (DCP): the SMPTE/DCI file package (Packing List, Composition Playlist, MXF track files) used to deliver encrypted JPEG 2000 movies to cinema servers, distinct from Interop DCP and IMF.
Digital citizen
Digital citizen: a person who participates in society through digital technologies. Key frameworks: Mossberger et al.'s ability to participate in society online, Ribble's nine elements, Council of Europe's 10 DCE domains; measured by competing scales.
Digital clock
A digital clock is a clock that displays the time as numerals rather than by hands on a dial, whether driven by quartz, mains power, or a flip mechanism.
Digital coding metasurface
A digital coding metasurface is a two-dimensional engineered surface whose unit cells act as digital phase bits, proposed in 2014 and used for beam steering and holography.
Digital coherent optics
A digital coherent optic (DCO) is a pluggable optical transceiver combining a coherent DSP, optics, and microprocessor in modules like QSFP-DD and OSFP, carrying DWDM wavelengths directly from router ports.
Digital Colony Partners
Digital Colony Partners, later renamed DigitalBridge Partners, is a private equity platform investing exclusively in digital infrastructure, including cell towers, fiber networks, and data centers.
Digital Combat Simulator
Digital Combat Simulator (DCS) is Eagle Dynamics' combat flight simulator series for Windows, from Su-27 Flanker (1995) and Lock-On (2003) to the free-to-play DCS World 2.9 with purchasable full-fidelity aircraft modules.
Digital contact tracing
Digital contact tracing is a public health surveillance method that uses smartphone apps, mostly Bluetooth-based, to notify people exposed to an infectious disease so they can test and isolate.
Digital control
Digital control is feedback control implemented by a digital computer or microcontroller, which samples signals and computes a control action, usually a discrete PID algorithm.
