Computer Terms & Abbreviations

Terms	Full Form	Definition
DNA	Distributed Internet Architecture	DNA is a marketing name for a collection of Microsoft technologies that enable the Windows platform and the Internet to work together.
DVR	Digital Video Recorder	DVR is an electronic device that records video in a digital format to a disk drive, USB flash drive, SD memory card, SSD or other local or networked mass storage device.
E-Commerce	Electronic Commerce	E-Commerce is a transaction of buying or selling online.
EDGE	Enhanced Data Rate for GSM (Global System for Mobile Communication) Evolution	EDGE is a digital mobile phone technology that allows improved data transmission rates as a backward-compatible extension of GSM.
EDI	Electronic Data Interchange	EDI is an electronic communication method that provides standards for exchanging data via any electronic means
EDP	Electronic Data Processing	EDP refer to the use of automated methods to process commercial data. Typically, this uses relatively simple, repetitive activities to process large volumes of similar information.
EDSAC	Electronic Delay Storage Automatic Calculator	EDSAC was an early British computer. Inspired by John von Neumann’s seminal First Draft of a Report on the EDVAC
EDVAC	Electronic Discrete Variable Automatic Compute	EDVAC was one of the earliest electronic computers. Unlike its predecessor the ENIAC, it was binary rather than decimal, and was a stored-program computer
EB	EXA BYTE	Exabyte (1 000 000 000 000 000 000 Bytes) = 109 GB
EiB	EXBI BYTE	1 EiB = 1.15 EXA BYTE
EROM/EPROM	Erasable Read Only Memory/Erasable Programmable Read Only Memory	It is a type of memory chip that retains its data when its power supply is switched off.
EEPROM	Electronically Erasable Programmable Read Only Memory	EEPROM is a type of non-volatile memory used in computers and other electronic devices to store relatively small amounts of data but allowing individual bytes to be erased and reprogrammed
E-Mail	Electronic Mail	E-Mail is a method of exchanging digital messages between people using digital devices such as computers, tablets and mobile phones.
EFS	Encrypted File System	EFS is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption. The technology enables files to be transparently encrypted to protect confidential data from attackers with physical access to the computer.
EDC	Electronic Digital Computer	EDC is a computer machine which is both an electronic computer and a digital computer.
ENIAC	Electronics Numerical Integrator And Calculator	ENAIC was amongst the earliest electronic general-purpose computers made. It was Turing-complete, digital, and could solve “a large class of numerical problems” through reprogramming.
FDC	Floppy Disk Controller	FDC is a special-purpose chip and associated disk controller circuitry that directs and controls reading from and writing to a computer’s floppy disk drive (FDD).
FDD	Floppy Disk Drive	FDD is a hardware device that reads data storage information. FDDs are used for reading and writing on removable floppy discs.
FORTRAN	Formula Translation	FORTRAN is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
FTP	File Transfer Protocol	FTP is a standard network protocol used for the transfer of computer files from a server to a client using the Client–server model on a computer network.
FS	File System	FS is the methods and data structures that an operating system uses to keep track of files on a disk or partition; that is, the way the files are organized on the disk.
FAT	File Allocation Table	FAT is a file system developed for hard drives that originally used 12 or 16 bits for each cluster entry into the file allocation table.
FPS	Frames Per Second	FPS is the frequency (rate) at which consecutive images called frames are displayed in an animated display. The term applies equally to film and video cameras, computer graphics, and motion capture systems.
FLOPS	Floating Point Operations Per Second	FLOPS is a measure of computer performance, useful in fields of scientific computations that require floating-point calculations
FM	Frequency Modulation.	FM is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. This contrasts with amplitude modulation, in which the amplitude of the carrier wave varies, while the frequency remains constant.
GB	Giga Byte	1GB = 109 Bytes
GiB	GIBIBYTE	1 GiB = 1.074 GB
GIF	Graphic Interchangeable Format	GIF is a bitmap image format which supports animations and allows a separate palette of up to 256 colors for each frame.
GDI	Graphical Device Interface	GDI is a Microsoft Windows application programming interface and core operating system component responsible for representing graphical objects and transmitting them to output devices such as monitors and printers.
GPRS	General Packet Radio Service	GPRS is a packet oriented mobile data service on the 2G and 3G cellular communication system’s global system for mobile communications (GSM).
