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-Subconnectors.

System Setup

Autility 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.

TAPI

Telephony Applications Programming Interface (API). Enables Microsoft Windows program applications to operate with a wide variety of telephony devices, including voice, data, fax, video, and so on.

TCP/IP

Transmission Control Protocol (TCP)/Internet Protocol (IP). The basic communication protocol of

the Internet. It can also be used in a private network. TCP/IP is a two-layer system. The higher layer, TCP, manages the assembling of a file into smaller packets that are transmitted by one computer over the Internet and received by the TCP layer on another computer. The receiving computer’s TCP layer reassembles the packets into the original message. The lower layer, IP, addresses each packet so that it gets to the right destination. See IP and IP Address.

Token Ring

A network communications protocol. See also Network Adapter.

TSR

Terminate-and-stay-resident. A program application that is loaded, stays in RAM after it is terminated, and can be reactivated by pressing a designated "hotkey" or a combination of keys. Examples of TSRs are calculators and calendars. OSs like Windows have the ability to constantly switch back and forth between applications and thereby do not require TSRs.

UDMA

Ultra DMA. A hard drive protocol that allows the computer to take advantage of fast Ultra ATA drives.

UL

Underwriters Laboratories, Inc. U.S. Federal law mandates that all equipment used in a place of business be certified as safe by a nationally recognized test laboratory. In addition, many local electrical and building codes and ordinances require that products be certified by a nationally recognized test laboratory. Because UL is one of the most widely recognized test laboratories in the United States, many customers of large manufacturers make UL approval a mandatory requirement.

UPS

Uninterruptible power supply. A device that allows your computer to keep running for a limited amount of time after the primary power source is lost. Typically, a UPS can also provide protection against power surges.
