EIA: Electronic Industries Association. A trade association that publishes technical standards related to the electronics industry.

emulation: A technique where a piece of hardware acts like another device.

erase: See delete.

escape: 1) A code ( ASCII code 27), signaling the computer that what follows are commands; used with peripheral devices such as printers and modems. 2) A means of aborting the task currently in progress.

escape guard time: A time before and after an escape code is sent to the modem which distinguishes between escapes that are part of the transmitted data, and escapes that are intended as a command to the modem.

execute: To interpret and execute instruction.

expanded memory: Memory, in addition to the 640 kilobytes of conventional memory managed by MS-DOS, that is mapped to a 64-kilobyte window between 640 kilobytes and 1 megabyte on the memory map. This memory is managed in accordance with the Expanded Memory Specification standard jointly developed by Lotus, Intel, and Microsoft called LIM-EMS.

extended memory: Memory, in addition to the 640 kilobytes of conventional memory managed by MS-DOS, that is mapped beyond 1 megabyte on the memory map.

firmware: A set of instructions built into the hardware which control and direct a microprocessorÕs activities.

fixed disk: See hard disk.

floppy disk: A small, flexible disk that stores magnetically encoded data used on a microcomputer. Also called a diskette.

floppy disk drive (FDD): An electro-mechanical device that reads and writes to floppy disks. See also floppy disk and diskette.

format: The process of readying a blank disk for its first use. Formatting establishes the structure of the disk that the operating system expects before it writes files or programs onto the disk.
