Glossary
mass storage
Any device used to
store large amounts of data. Usually
refers to hard disks and tape backup
units.
memory modules
Miniature boards
containing memory chips. Used for
increasing the amount of memory
available in the computer.
multimedia
Combining static media
(such as text and pictures) with
dynamic data (such as sound, video,
and animation) on the same system.
network server mode
A security
feature that prevents unauthorized
use of an input device (like a
keyboard or mouse) while your
computer is running as an unattended
network server.
pixel
Picture element. The smallest
addressable spot on the screen.
POST
Power-On-Self-Test. A series
of tests your computer performs
when you switch the computer on.
RAM
Random Access Memory. This
memory is used to hold programs and
data temporarily.
resolution
A measure of the visible
detail on a screen or printout. Screen
resolution is measured in ‘pixels
across’ by ‘pixels down’ by ‘number of
colors’. Printer resolution is measured
in dpi (dots-per-inch).
ROM
Read-Only Memory. Computer
memory used to store parts of the
computer’s operating system
permanently. ROM chips can contain
instructions and data.
SCSI
Small Computer System
Interface. A high-speed data bus used
for connecting hard disks, tape drives,
and other accessories to your
computer.
SCSI chain
Devices connected on a
single SCSI bus.
Setup
program
Used to inform the
computer about its configuration, for
example the amount of memory
installed. The setup program is stored
in ROM on the system board.
shadow RAM
A method of
relocating the system and/or video
BIOS from slower ROM chips to faster
RAM to improve system performance.
SIMM
Single In-line Memory
Module. A small board containing
several RAM chips.
terminator
A resistor at the end of a
SCSI cable that prevents the signal
from reflecting back along the cable.
video controller
A chip or
expansion card which converts
signals in the computer into
displayable signals.
video RAM
Memory that enables or
speeds up drawing to the screen or
increases resolution or color options.
