Editable PostScript: PostScript commands that have been translated into a text file, which can then be changed without the need to use the applications program from which the PostScript file was originally created.
EISA: See Extended Industry Standard Architecture
Electron Gun: The device in the CRT that produces the electron beam that activates the phosphors, causing them to emit red, green and blue light.
Electronic Mail (eMail): A message service that uses telecommunications and electronics to deliver soft or hard copy information.
Electrophotographic Printing: The technology used in copy machines and laser printers. An electrically charged drum is hit with small beams of light Wherever the light hits, the drum loses its electrical charge. When toner is applied, its sticks to the non-charged parts of the drum. Paper is then pressed against the drum, and the toner adheres to the paper. The paper is then heated to "set" the toner.
Electrostatic Printing: Printing process that uses a special paper which is charged by an electron beam. The tone sticks to the charged areas. Used in large-image plotters.
Ellipsis: Three equally spaced periods, used to indicate omitted or missing material, especially in quoted text.
Elliptical Dot: Also called a chain dot. Used in a halftone to achieve some of the smoothness of a round dot without sacrificing the sharpness of the square dot. This dot shape improves the gradation of middletones and especially skin tones. Most useful in reproducing color for cosmetic and fashion illustrations.
Em: A relative measurement of horizontal space _ it's a measurement because it is equal to the width of a capital "M". It's "relative" because it's the width of the capital "M" in whatever font and size you're dealing with.
Emacs: A powerful, programmable text editor common on many UNIX systems.
EMS Memory: A type of expanded memory available on systems that conform to the Lotus-Intel-Microsoft Expanded Memory Specification (LIM EMS).
Emulation Mode: A mode in which a device such as a printer can imitate the behavior of a different device.
Emulsion Side: In photography, the side of the film coated with the silver halide emulsion which faces the lens during exposure. It is the most susceptible to scratches. In photographic sheet film, there is usually a code notch indicating what type of film it is as well as which side the emulsion is on.
En: Half the width on an em.
Encapsulated PostScript: An image description format. EPS translates graphics and text into descriptions to a printer of how to draw them. The font and pictures themselves need not be loaded into the printer; they've been "encapsulated" into the EPS code.
Encode: The term used to describe the translation of information, suchas text or photographs, into binary code.

Enhanced Metafile: An intermediate file format, consisting of GDI objects and commands, used in the Windows 95 printing system.
Expanded Memory: Memory in addition to conventional memory that is available for applications. It is allocated in 16K blocks.
Extended Industry Standard Architecture (EISA): An enhancment to the bus architecture used on the IBM PC/AT, which allows the use of 32-bit devices in the same type of expansion slot used by an ISA adapter card. EISA slots and adapters were formerly common in server computers, but have been mostly replaced with PCI slots.
End Caps: Symbolss, such as an arrowhead or bullet, used to cap the end of a line of text.
Erase: Erasing computer memory changes specified binary data in storage with zeros or other null codes. Erasing has the effect of clearing the storage area.
Ethernet: A network access method developed by Digital Equipment Corporation, Intel, and Xerox in the early 1970s, Ethernet is the most widely used local-area network technology available today. This standard is capable of linking up to 1024 nodes.
Exabyte: An eight-millimeter, two-gigabyte tape drive providing substantial data storage and archiving on a small cartridge. It is more cost effective than standard magnetic tapes, as fewer Exabyte tapes are required to store information.
Expansion Bus: The main "data pathway" inside a computer, usually fitted with slots which will accept circuit boards (cards) to expand and enhance the capabilities of the computer.
Expansion Slot: A long, thin socket mounted in an expansion bus, which accepts an expansion card.
Export: To save data in a form that another program can read. If you are using an illustration program, you may choose to export your work to a desktop publishing programs as an EPS file, for example.
Exposure: The step in photographic processes during which light produces an image on the light-sensitive film coating.
Extended Memory: Memory in addition to conventional memory that is not readily accessible to MS-DOS or MS-DOS applications. Extended memory cannot be used on older PC's, such as 8086/88 computers.
Extranet: A private, secure extension of a corporate intranet that allows organizations to build a persistent network link with customers, vendors, or other business partners.
