RS-232

Along-established standard describing the interface for serial data communication between computers and related devices. See also DCE and DTE.

RTC

Real-time clock. Battery-powered clock circuitry on the system board that keeps the date and time after you turn off the computer.

RTCRST

Real-time clock reset. A jumper on the system board that can often be used for troubleshooting problems.

SCSI

Small computer system interface. A high-speed interface that can be used to connect devices to a computer, such as hard drives, CD drives, printers, and scanners. The SCSI can connect up to seven devices using a single controller. Each device is accessed by an individual ID number on the SCSI controller’s bus. See also LVD.

SDRAM

Synchronous dynamic random-access memory

(DRAM). A type of DRAM used on DIMMs. SDRAM is synchronized with the system clock speed, operating at the same speed as the system bus.

sec

Second(s). A measurement of time.

Serial Port

An I/O port on your computer that transfers data sequentially, one bit at a time. It uses either a 9-pin or a 25-pin, male subminiature-Dconnector, typically to connect a device such as a modem or mouse. Also referred to as a COM port. See also DCE and DTE.

Service Tag Number

Afive to seven-digit alpha-numeric code located on a sticker on your Dell computer. This code is programmed into your computer’s system setup by Dell during the manufacturing process. Dell

customer support applications use the Service Tag to display all of the configuration and support history information for your specific computer. See also Express Service Code. For more information, see http://support.dell.com.

SIMM

Single in-line memory module. A slim circuit board containing RAM chips. SIMMs can be plugged into sockets on the computer's system board to add memory to the computer. Depending on the computer, SIMMs may need to be installed in multiples of two or four. See also DIMM and RIMM.

SMART

Self-Monitoring And Reporting Tool. A standard for developing hard drives and software systems that automatically monitors a hard drive's health and reports potential problems. Ideally, this should allow you to take proactive actions to prevent impending hard-drive failures.

SMBIOS

System management BIOS. A standard method by which the BIOS data of a WfM-compliant computer can be accessed remotely.

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.
