SNMP
Simple Network Management Protocol. The protocol governing network
management and the monitoring of network equipment.
SPGA
Staggered pin grid array. A type of socket for a computer chip . The SPGA
socket has all its pins in staggered rows, as opposed to the PGA socket, which
has its pins lined up in even rows.
SPX
Sequenced packet exchange. A transport layer protocol that works with IPX to
ensure reliable data transmissions. See also IPX/SPX .
SRAM
Static random-access memory ( RAM ). Referred to as “static” because it retains
a value as long as power is supplied, unlike DRAM , which must be refreshed
regularly.
Stepping
A term used to indicate a manufacturing “version number” or “revision level”
of an Intel microprocessor . The initial version of a new processor is the A0
step. As revisions are made for functional fixes or manufacturing
improvements, the stepping is increased. Intel recommends using identical
steppings of processors in dual-processor systems.
STP
Shielded twisted pair. A common type of copper wiring used for Ethernet
networks. STP wiring is constructed just like UTP , having two insulated
copper wires wound around each other to form a “twisted pair.” However, for
some business locations, twisted pairs are also enclosed in a shield that
functions as a ground.
Subminiature-D
D-shaped connectors on your computer that typically have 9, 15, or 25 pins
and can be male or female. Also referred to as D-Sub connectors.
System Setup
A utility that allows you to configure user-selectable options in the BIOS such
as date and time, or system password, as well as to set the current configuration
information, including the amount of memory or type of hard drive installed.
