semiconductor on and the other off.
There is no current flow except for
capacitance charging and
discharging and for switching
operations. CMOS devices therefore
use considerably less power than
other types of semiconductor
devices. They are ideal for use in
microcomputers and
battery-powered devices such as
calculators and portable computers.
computer architecture
. (1) The
logical structure and functional
characteristics of a computer,
including the interrelationships
among its hardware and software
components. (2) The organizational
structure of a computer system,
including hardware and software.
configuration . The manner in
which the hardware and software of
an information processing system
are organized and interconnected.
(T)
configure . To set up a computer
for operation by describing to the
system the devices, optional
features, and programs installed in
the computer.
connector . An electrical part used
to join two or more other electrical
parts. (Contrast with port.)
control . The determination of the
time and order in which the parts of
a computer and the devices that
contain those parts perform the
input, processing, storage, and
output functions.
controller . A device that
coordinates and controls the
operation of one or more
input/output devices, such as
workstations, and synchronizes the
operation of such devices with the
operation of the system as a whole.
crossover cable . A type of
10BASE-T cable in which the
transmit and receive data pairs are
wired so that the transmit pair is
terminated at the pin positions used
by the receive pair at the opposite
end of the cable. A crossover cable
is used to connect the 10BASE-T
port on an Ethernet controller to a
10BASE-T port on a repeater that
does not perform the crossover
function.
D
DASD . Direct access storage
device.
data . (1) A re-interpretable
representation of information in a
formalized manner suitable for
communication, interpretation, or
processing. Operations can be
performed upon data by humans or
by automatic means. (T) (2) Any
representations such as characters or
analog quantities to which meaning
is or might be assigned. (A)
data bus . A bus used to
communicate data internally and
externally to and from a processing
unit, storage, and peripheral
devices. (A)
