	Glossary
SCSA	Signal Computing System Architecture. A hardware model for
	computer telephony servers. A key SCSA element is a TDM (time
	division multiplexed) telephony bus for voice and video signals,
	known as the SCbus™ in VME implementations of this architecture.
SCSI	Small Computer Systems Interface. An industry-standard high-
	speed interface primarily used for secondary storage. SCSI-1
	provides up to 5 Mbps data transfer.
SCSI-2 (Fast/Wide)	An improvement over plain SCSI; and includes command queuing.
	Fast SCSI provides 10 Mbps data transfer on an 8-bit bus. Wide
	SCSI provides up to 40 Mbps data transfer on a 16- or 32-bit bus.
serial port	A connector that can exchange data with an I/O device one bit at a
	time. It may operate synchronously or asynchronously, and may
	include start bits, stop bits, and/or parity.
SIM	Serial Interface Module
SIMM	Single Inline Memory Module. A small circuit board with RAM
	chips (normally surface mounted) on it designed to fit into a standard
	slot.
SIO	Super I/O controller
SMT	Surface Mount Technology. A method of mounting devices (such as
	integrated circuits, resistors, capacitors, and others) on a printed
	circuit board, characterized by not requiring mounting holes. Rather,
	the devices are soldered to pads on the printed circuit board.
	Surface-mount devices are typically smaller than the equivalent
	through-hole devices.
software	A computing system is normally spoken of as having two major
	components: hardware and software. Software is the term used to
	describe any single program or group of programs, languages,
	operating procedures, and documentation of a computer system.
	Software is the real interface between the user and the computer.
SRAM	Static Random Access Memory
TDM	Time Division Multiplexing. A multiplexing scheme in which
	individual I/O ports or channels share slices of time on an aggregate
	channel, Receivers and transmitters are synchronized. The SCbus™
	is a TDM implementation that provides up to 2048 time slots, the
	equivalent of 1024 voice conversations at 64 Kbps.
thick Ethernet	See 10base-5.
