FRSURFHVVRU
A coprocessor relieves the computer’s
microprocessor of specific processing
tasks. A math coprocessor, for example,
handles numeric processing. A graphics
coprocessor handles video rendering. The
Intel
®
Pentium
®
microprocessor includes a
built-in math coprocessor.
FSL
Abbreviation for characters per inch.
&38
Abbreviation for central processing unit.
See also microprocessor.
FXUVRU
In character-based MS-DOS programs,
the cursor is usually a block or an under-
score (possibly blinking) that represents
the position at which the next character
typed will appear. Windows programs can
design their own cursors—common cur-
sor symbols include the pointer arrow and
the text-insertion I-beam.
'$&
Acronym for digital-to-analog converter.
'$7
Acronym for digital audio tape.
G%
Abbreviation for decibel(s).
G%$
Abbreviation for adjusted decibel(s).
'&
Abbreviation for direct current.
''&
Acronym for display data channel. A
VESA
®
standard mechanism that allows
the system to communicate with the
monitor and retrieve information about its
capabilities.
GHYLFHGULYHU
A device driver allows the operating sys-
tem or a program to interface correctly
with a peripheral such as a printer or net-
work card. Some device drivers—such as
network drivers—must be loaded from
the config.sys file (with a device= state-
ment) or as memory-resident programs
(usually, from the autoexec.bat file). Oth-
ers—such as video drivers—must load
when you start the program for which they
were designed.
'+&3
Acronym for Dynamic Host Configuration
Protocol.
GLDJQRVWLFV
See diskette-based diagnostics.
',00
Acronym for dual in-line memory
module.
',1
Acronym for
Deutsche Industrie Norm

',3
Acronym for dual in-line package. A circuit
board, such as a system board or expan-
sion card, may contain DIP switches for
configuring the circuit board. DIP switch-
es are always toggle switches, with an
ON position and an OFF position.

Directories help keep related files orga-
nized on a disk in a hierarchical, “inverted
tree” structure. Each disk has a “root”
directory; for example, a
C:\> prompt nor-
mally indicates that you are at the root
directory of hard-disk drive C. Additional di-
rectories that branch off of the root directory
are called
subdirectories
. Subdirectories
may contain additional directories branching
off of them.
