device, such as a diskette drive,
hard disk drive, or CD-ROM drive,
in which access time is effectively
independent of the location of the
data on the storage medium.
direct memory access (DMA) . The
transfer of data between memory
and input/output devices without
microprocessor intervention.
diskette . A small magnetic disk
enclosed in a jacket. (T)
diskette drive . The mechanism
used to seek, read, and write data
on diskettes. It can be installed in,
or attached to, a computer.
display . A component capable of
displaying information on a viewing
surface; for example, a cathode ray
tube or a gas panel.
DMA . Direct memory access.
duplex . Pertaining to
communication in which data can
be sent and received at the same
time. Synonymous with full-duplex
(FDX).. Contrast with half-duplex
(HDX).
E
ECC . Error correcting code.
EEPROM . Electrically erasable
programmable read-only memory.
EISA . Extended industry standard
architecture.
electrically erasable programmable
read-only memory (EEPROM)
.
EPROM that can be reprogrammed
while it is in the computer.
EPROM . Erasable programmable
read-only memory.
erasable programmable read-only
memory (EPROM)
. A PROM that
can be erased by a special process
and reused. (T)
extended industry standard
architecture (EISA)
. An expansion
bus architecture used in a network
server that provides compatibility
among hardware components.
F
FDX . Full-duplex. Synonymous
with duplex. Contrast with HDX.
file . A named set of records stored
or processed as a unit. (T)
flash memory . See electrically
erasable programmable read-only
memory (EEPROM).
frame . (1) A data structure that
consists of fields, predetermined by
a protocol, for the transmission of
user data and control data. The
composition of a frame, especially
the number and types of fields, may
vary according to the type of
protocol. (T)
frequency . The rate of signal
oscillation, expressed in hertz.
