SYNCHRONOUS WORKING
In automatic data processing, a general term for a
specification of a process to be performed on data,
e.g. an ordered collection of instructions and other
data associated with the instructions.
That part of a card track where a punched card is
punched.
That part of a card track where the data on a
punched card is read.
The useful part of what is transmitted from a source
to destinations in order to convey data.
It can be
initiated and controlled at the source and recognized
at a destination.
A part of a machine where punched cards are
deposited after passing through the machine.
The
retention of data for subsequent reference.
A device intended for storage.
The prOperties of
a store depend upon the purposes for which it is
intended; . thus a store forming part of an automatic
data processing equipment (an INHERENT STORE,
computer store or automatic store) may be con-
trolled automatically,
i.e.
without human inter-
vention.
If the storage medium is a data carrier
(as in a DATA CARRIER STORE), some action by
an operator is needed (e.g. selection and loading)
before automatic control becomes possible.
The performance of a sequence of operations con-
trolled by regularly spaced clock signals.
Note:
A sequence of operations controlled syn-
chronously may form one of a sequence of larger
operations working asynchronously.
