DOS	(Disk Operating System) See operating system.
DRAM	(Dynamic RAM) See RAM.
E
ECC	(Error Checking and Correction) A method of detecting and
	correcting errors.
EEPROM	(Electrically Erasable Programmable Read-Only Memory) A type
	of memory device that stores password and configuration
	information.
EGA	(Enhanced Graphics Adapter) A type of video display system that
	provides medium-resolution text and graphics on TTL
	monochrome, color, and enhanced color monitors.
EISA	(Extended Industry Standard Architecture) An industry
	standard for computers and circuit cards that transfer 32 bits of
	data at a time.
EMI	(Electromagnetic Interference).
EMS	(Expanded Memory Specification) A method of accessing memory
	beyond the 640K limit of DOS by exchanging data in and out of
	main memory at high speeds. Some software requires EMS to
	operate.
EPROM	(Erasable Programmable Read-Only Memory) A type of memory
	device that is usually used to store system BIOS code. This code
	can be erased with ultraviolet light, but is not lost when the
	computer is powered off. See also flash EPROM and ROM.
ESD	(Electrostatic Discharge).
expanded memory	See EMS.
expansion slot	See backplane slot.
extended memory	The protected memory above 1M that is directly accessible by the
	microprocessor through certain utilities and operating systems.
	This memory is used in computers with 80286, 80386, and 80486
	microprocessors.
F
flash EPROM	A type of memory device that is usually used to store system
	BIOS code. This code can be replaced with updated code from a
	floppy disk, but is not lost when the computer is powered off. See
	also EPROM and ROM.
floppy disk drive	See disk drive.
format	The process used to organize a hard or floppy disk into sectors so
	it can accept data. Formatting destroys all previous data on the
	disk.
