EIDE	Enhanced Integrated Drive Electronics. An improved version of
	IDE, with faster data rates, 32-bit transactions, and DMA. Also
	known as Fast ATA-2.
EISA (bus)	Extended Industry Standard Architecture (bus) (IBM). An
	architectural system using a 32-bit bus that allows data to be
	transferred between peripherals in 32-bit chunks instead of 16-bit or
	8-bit that most systems use. With the transfer of larger bits of
	information, the machine is able to perform much faster than the
	standard ISA bus system.
EPROM	Erasable Programmable Read-Only Memory. A memory storage
	device that can be written once (per erasure cycle) and read many
	times.
ESD	Electro-Static Discharge/Damage
Ethernet	A local area network standard that uses radio frequency signals
	carried by coaxial cables.
Falcon	The DRAM controller chip developed by Motorola for the
	MVME2600 and MVME3600 series of boards. It is intended to be
	used in sets of two to provide the necessary interface between the
	Power PC60x bus and the 144-bit ECC DRAM (system memory
	array) and/or ROM/Flash.
fast Ethernet	See 100Base-TX.
FDDI	Fiber Distributed Data Interface. A network based on the use of
	optical-fiber cable to transmit data in non-return-to-zero, invert-on-
	1s (NRZI) format at speeds up to 100 Mbps.
firmware	The program or specific software instructions that have been more
	or less permanently burned into an electronic component, such as a
	ROM (read-only memory) or an EPROM (erasable programmable
	read-only memory).
hardware	A computing system is normally spoken of as having two major
	components: hardware and software. Hardware is the term used to
	describe any of the physical embodiments of a computer system,
	with emphasis on the electronic circuits (the computer) and
	electromechanical devices (peripherals) that make up the system.
IDE	Integrated Drive Electronics. A disk drive interface standard. Also
	known as ATA (Advanced Technology Attachment).
IEEE	Institute of Electrical and Electronics Engineers
