The Digital East Fund, originally Earlybird Digital East, is a venture capital fund launched in 2014 for seed and Series A investments from the Baltics through Central and Eastern Europe to Turkey.
Digital economy
The digital economy, also called the internet economy, is the part of the economy based on digital technologies, worth $2.41 trillion, about 10% of US GDP, in 2021.
Digital Economy Partnership Agreement
The Digital Economy Partnership Agreement (DEPA) is a standalone digital trade agreement signed by Chile, New Zealand, and Singapore, with a modular design that lets other economies adopt parts or accede.
Digital electronics
Digital electronics, also called digital circuits, is the branch of electronics that represents information with discrete binary values and processes it with logic gates and memory.
Digital elevation model
A digital elevation model (DEM) is a digital representation of the Earth's bare-ground topographic surface, excluding trees and buildings, used in flood modeling, road design, and topographic mapping.
Digital ELISA
The single-molecule array (Simoa) is a digital ELISA technology commercialized by Quanterix that counts individual enzyme-labeled protein complexes in femtoliter wells, roughly 1,000-fold more sensitive than conventional immunoassays.
Digital Equipment Corporation
Digital Equipment Corporation (DEC), marketed as Digital, was an American computer company founded in 1957 that became the world's second-largest computer company and leading minicomputer maker.
Digital ethnography
Digital ethnography, also known as netnography, is a qualitative research method that studies culture and social interaction through participant observation and immersion in online communities, used most often in marketing and consumer research.
Digital Experience Monitoring
Digital experience monitoring (DEM) is a performance discipline measuring the availability, performance, and quality of user experience of applications, combining real-user monitoring and synthetic transaction monitoring; Gartner defined the category in 2016.
Digital Extremes
Digital Extremes, Canadian game studio founded by James Schmalz in 1993 in London, Ontario; maker of Epic Pinball, the Unreal series with Epic Games, Dark Sector, The Darkness II, and Warframe (2013, 85+ million players); Tencent-owned since 2020; developing Soulframe.
Digital factory
A digital factory is a network of digital models, methods, and tools for planning, implementing, and continuously improving a factory, defined by the VDI in the early 2000s.
Digital filter
A digital filter is a system that computes an output from a sampled, discrete-time input signal using arithmetic, classified as FIR filters with fixed responses and IIR filters with feedback.
Digital footprint
A digital footprint, also called a digital trail or data trail, is the data trail a person creates online, divided into active and passive footprints.
Digital forensics
Digital forensics, also called forensic computing, is the branch of forensic science that recovers and analyzes data from computers and mobile devices for legal proceedings.
Digital Fortress
Digital Fortress (1998) is Dan Brown's debut techno-thriller, set at the NSA, where cryptographer Susan Fletcher confronts an unbreakable code by Ensei Tankado that is actually a worm; noted for cryptography inaccuracies.
Digital Health
Digital health is the use of digital technologies to improve health, an umbrella term the World Health Organization applies to eHealth, mHealth, telemedicine, big data, genomics, and artificial intelligence.
Digital history
Digital history is the use of computers, software, and computational methods such as text mining, network analysis, and GIS to examine and represent the past.
Digital holographic microscopy
Digital holographic microscopy (DHM) is a label-free optical technique that numerically reconstructs holograms of microscopic samples into quantitative phase and amplitude images, notably of living cells.
Digital holography
Digital holography is an imaging technique in which a hologram is recorded on a digital sensor and reconstructed numerically, recovering both intensity and phase of the wavefield.
Digital Horizon
Digital Horizon is a London-based venture capital firm founded in 2018 by Alan Vaksman, investing in fintech and enterprise software startups across Europe, America, and Israel.
Digital humanities
Digital humanities (DH), formerly humanities computing, applies computational methods to human culture, from Busa's 1946 Index Thomisticus to machine learning and generative AI, while debating its own critical and disciplinary identity.
Digital humanities centre
A digital humanities center is a university-based research organization that applies computational methods to humanities scholarship and humanities methods to digital phenomena, ranging from small research groups to pan-European infrastructures.
Digital image
A digital image is a picture represented as a finite array of pixels, each storing a quantized value of light intensity or color. The first was made in 1957.
Digital image correlation
Digital image correlation (DIC) is a non-contact optical method that tracks a speckle pattern through image sequences to measure full-field displacement and strain, introduced in 1982.
Digital image processing
Digital image processing is the branch of signal processing that uses computers to enhance, transform, and analyze images, born in the early 1960s with NASA's Ranger 7 Moon pictures.
Digital India
Digital India is a flagship Government of India program launched by Prime Minister Narendra Modi on 1 July 2015, coordinated by MeitY to build digital infrastructure and services.
Digital instrumentation and control
Digital instrumentation and control is the use of computer-based systems, rather than analog devices, to monitor and protect nuclear power plants; software common-cause failure is its central technical concern.
