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.
