Glossary 13
that timing signals have been set up
correctly.
In equivalent configurations, a computer
with SDRAM will have faster memory per-
formance than a computer with EDO
memory.
VHF
Abbreviation for second(s).
6(&
Abbreviation for single-edge contact.
Newer Intel processors, such as the Pen-
tium II processor, use this type of
connector as an interface between the
processor and the system board.
VHULDOSRUW
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.
VHUYLFHWDJQXPEHU
A bar code label on the computer that
identifies it when you call Dell for custom-
er or technical support.
VKDGRZLQJ
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.
6,0'
Abbreviation for Single Instruction Multi-
ple Data.
6,00
Acronym for single in-line memory mod-
ule. A small circuit board containing
DRAM chips that connects to the system
board.
60$57
Acronym for Self-Monitoring Analysis and
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 technol-
ogy, you must have a SMART-compliant
hard-disk drive and the proper support in
the system BIOS.
6103
Abbreviation for Simple Network
Management Protocol. SNMP is an
industry-standard interface that allows a
network manager to remotely monitor
and manage workstations.
65$0
Abbreviation for static random-access
memory. Because SRAM chips do not re-
quire continual refreshing, they are
substantially faster than DRAM chips.
656
Abbreviation for sound retrieval system.
69*$
Abbreviation for super video graphics ar-
ray. VGA and SVGA are video standards
for video adapters with greater resolution
and color display capabilities than previ-
ous standards.
To display a program at a specific resolu-
tion, you must install the appropriate
video drivers and your monitor must sup-
port the resolution. Similarly, the number
of colors that a program can display de-
pends on the capabilities of the monitor,
the video driver, and the amount of video
memory installed in the computer.
VZLWFK
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.
V\QWD[
The rules that dictate how you must type
a command or instruction so that the com-
puter understands it.
