	Glossary
ISA (bus)	Industry Standard Architecture (bus). The de facto standard system
	bus for IBM-compatible computers until the introduction of VESA
	and PCI. Used in the reference platform specification. (IBM)
ISASIO	ISA Super Input/Output device
ISDN	Integrated Services Digital Network. A standard for digitally
	transmitting video, audio, and electronic data over public phone
	networks.
LAN	Local Area Network
LED	Light-Emitting Diode
little-endian	A byte-ordering method in memory where the address n of a word
	corresponds to the least significant byte. In an addressed memory
	word, the bytes are ordered (left to right) 3, 2, 1, 0, with 3 being the
	most significant byte.
MPC603, MPC604	Motorola’s component designations for the PowerPC 603 and
	PowerPC 604 microprocessors.
MPIC	Multi-Processor Interrupt Controller
MPU	MicroProcessing Unit
nonvolatile memory	A memory in which the data content is maintained whether the
	power supply is connected or not.
NVRAM	Non-Volatile Random Access Memory
OEM	Original Equipment Manufacturer
OS	Operating System. The software that manages the computer
	resources, accesses files, and dispatches programs.
parallel port	A connector that can exchange data with an I/O device eight bits at
	a time. This port is more commonly used for the connection of a
	printer to a system.
PCI (local bus)	Peripheral Component Interconnect (local bus) (Intel). A high-
	performance, 32-bit internal interconnect bus used for data transfer
	to peripheral controller components, such as those for audio, video,
	and graphics.
PCMCIA (bus)	Personal Computer Memory Card International Association (bus).
	A standard external interconnect bus which allows peripherals
	adhering to the standard to be plugged in and used without further
	system modification.
