SPX
Sequenced packet exchange
. A transport layer protocol that works with IPX to
ensure reliable data transmissions. See also IPX/SPX .

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.
