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. sec Abbreviation for second(s). serial port An I/O port used most often to connect a modem to your computer. You can usually identify a serial port on your computer by its 9-pin connector. service tag number A bar code label on the computer that identifies it when you call Dell for customer or 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. SIMM Acronym for single in-line memory module. A small circuit board containing DRAM chips that connects to the system board. SMART Acronym for Self-Monitoring Analysis Reporting Technology. A technology that allows hard-disk 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-disk 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 computer. switch On a computer system board, switches control various circuits or functions in your computer 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.

circuitry inside the computer that keeps the date and time
after you turn off the computer.
SCSI

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

serial port
An I/O port used most often to connect a modem to your
computer. You can usually identify a serial port on your

service tag number
A bar code label on the computer that identifies it when
you call Dell for customer or 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.
SIMM
Acronym for single in-line memory module. A small
circuit board containing DRAM chips that connects to the
system board.
SMART
Acronym for Self-Monitoring Analysis Reporting
Technology. A technology that allows hard-disk 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-disk 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 chips do not require continual refreshing, they are

a program can display depends on the capabilities of the
monitor, the video driver, and the amount of video memory
installed in the computer.
switch
On a computer system board, switches control various
circuits or functions in your computer 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 computer understands it.
