Glossary-9
Glossary
computer system:
A combination of hardware, software, firmware, and peripheral
components assembled to process data into useful information.
configuration:
The specific components in your system (such as the terminal,
printer, and disk drives) and the settings that define how your system works.
You use the HW Setup program to control your system configuration.
controller:
Built-in hardware and software that controls the functions of a specific
internal or peripheral device (e.g. keyboard controller).
CPU:
Central Processing Unit. The portion of the computer that interprets and
executes instructions.
CRT:
Cathode Ray Tube. A vacuum tube in which beams projected on a
fluorescent screen-producing luminous spots. An example is the television set.
cursor:
A small, blinking rectangle or line that indicates the current position on the
display screen.
D
data:
Information that is factual, measurable or statistical that a computer can
process, store, or retrieve.
data bits:
A data communications parameter controlling the number of bits (binary
digits) used to make up a byte. If data bits = 7 the computer can generate
128 unique characters. If data bits = 8 the computer can generate 256 unique
characters.
DC:
Direct Current. Electric current that flows in one direction. This type of power
is usually supplied by batteries.
default:
The parameter value automatically selected by the system when you or
the program do not provide instructions. Also called a preset value.
delete:
To remove data from a disk or other data storage device. Synonymous
with erase.
device driver:
A program (called a “driver”) that permits a computer to
communicate with a device.
dialog box:
A window that accepts user input to make system settings or record
other information.
disable:
To turn a computer option off. See also enable.
disk drive:
The device that randomly accesses information on a disk and copies
it to the computer’s memory. It also writes data from memory to the disk. To
accomplish these tasks, the unit physically rotates the disk at high speed past
a read-write head.
disk storage:
Storing data on magnetic disk. Data is arranged on concentric
tracks much like a phonograph record.
display:
A CRT, LCD, or other image producing device used to view computer
output.
