RTC
Abbreviation for real-time clock. Battery-powered clock circuitry inside the system that keeps the date and time after you turn off the system.
SCSI
Acronym for small computer system interface. An I/O bus interface with faster data transmission rates than standard ports. You can connect up to seven
devices (15 for some newer SCSI types) to one SCSI interface.
SDMS
Abbreviation for SCSI device management system.
SDRAM
Acronym for synchronous dynamic random-access memory.
sec
Abbreviation for second(s).
SEC
Abbreviation for single-edge contact.
serial port
An I/O port used most often to connect a modem to your system. You can usually identify a serial port on your system by its 9-pin connector.
service tag number
A bar code label on the system that identifies it when you call for technical support.
shadowing
A computer's system and video BIOS code is usually stored on ROM chips. Shadowing refers to the
performance-enhancement technique that copies BIOS code to faster RAM chips in the upper memory area (above 640 KB) during the boot routine.
SIMD
Abbreviation for Single Instruction Multiple Data.
SMART
Acronym for Self-Monitoring Analysis and Reporting Technology. A technology that allows hard drives to report errors and failures to the system BIOS, which
then displays an error message on the screen. To take advantage of this technology, you must have a SMART-compliant hard drive and the proper support in
the system BIOS.
SNMP
Abbreviation for Simple Network Management Protocol. SNMP is an industry-standard interface that allows a network manager to remotely monitor and
manage workstations.
SRAM
Abbreviation for static random-access memory. Because SRAM chips do not require continual refreshing, they are substantially faster than DRAM chips.
SVGA
Abbreviation for super video graphics array. VGA and SVGA are video standards for video adapters with greater resolution and color display capabilities than
previous standards.
To display a program at a specific resolution, you must install the appropriate video drivers and your monitor must support the resolution. Similarly, the number
of colors that a program can display depends on the capabilities of the monitor, the video driver, and the amount of video memory installed in the system.
switch
On a system board, switches control various circuits or functions in your system. These switches are known as DIP switches; they are normally packaged in
groups of two or more switches in a plastic case. Two common DIP switches are used on system boards: slide switches and rocker switches. The names of the
switches are based on how the settings (on and off) of the switches are changed.
syntax
The rules that dictate how you must type a command or instruction so that the system understands it.
system board
As the main circuit board, the system board usually contains most of your system's integral components, such as the following:
l Microprocessor
l RAM
