DEFINITION OF UNUSUAL TERMS (cont)
Buffer
A digital circuit with one input and one output. The
output is the same as the input.
Bus
Two or more conductors running in parallel, used for
carrying information or voltages.
Byte
A group of adjacent bits formed for convenience in
transmitting and receiving data. Usually it takes more
than on byte to make a word.
Clock
Clock frequency
Clock rate
Collimator
Crowbar
Desiccant
EPROM
Flag
Flip-flop
The primary source of synchronizing signals in
electronic computers.
In digital computers, the master frequency of periodic
pulses that are used to schedule the operation of the
computer.
The rate at which a word or characters of a word (bits)
are transferred from one internal computer element to
another.
Clock rate is expressed in cycles.
An optical device that creates a beam made of parallel
rays of light used in testing and adjusting certain
optical instruments.
The action which effectively creates a high overload on
the actuating part of the protective device. This
crowbar action may be triggered by a slight increase in
current or voltage.
A drying agent.
An IC memory chip whose stored data can be read at
random.
The data can be erased and new data can be
stored, but only by a special system other than the one
in which the memory is used.
A bit stored in a certain place, which the system uses
as a “reminder” of something that has been done or
something that needs to be done.
A building-block having two stable states that stores
one bit by means of two gates “cross-coupled” as a
latch, with the output of each forming an input to the
other.
