Segment to SQE

Segment	A portion of a network which is separated from other
	networks. A segment may be one portion of a bridged,
	switched, or routed network. Segments must be capable of
	operating as their own networks, without requiring the
	services of other portions of the network.
Server	A workstation or host device that performs services for
	other devices (clients) on the network.
SIMM	Single In-line Memory Module. A collection of Random
	Access Memory microprocessors which are placed on a
	single, replaceable printed circuit board. These SIMMs
	may be added to some devices to expand the capacity of
	certain types of memory.
Single Mode	A type of fiber optics in which light travels in one
	predefined mode, or wavelength. Signals in single mode
	fiber optics are typically driven by lasers. The use of lasers
	and the transmission characteristics of single mode fiber
	optics allow the media to cover greater distances than
	multimode fiber optics.
SMA	Sub-Miniature Assembly. A modular connector and port
	system used in multimode fiber optic cabling. The SMA
	connector is threaded, and is screwed into an SMA port.
SNMP	Simple Network Management Protocol. SNMP is a
	standardized set of network monitoring tools. See also
	RMON.
Spanning Tree	A mathematical comparison and decision algorithm
	performed by Ethernet bridges at power-up. Spanning tree
	detects the presence of data loops and allows the bridges to
	selectively activate some ports while others remain in a
	standby condition, avoiding the data loops and providing
	redundant paths in the event of bridge failures.
SQE	Signal Quality Error. A self-monitoring test performed by
	some Ethernet equipment which examines the status of the
	device’s connection to the network at arbitrary and
	predefined intervals.
