static memory. RAM memory using flip-flops as the memory
elements. Data is retained as long as power is applied to the
flip-flops. Contrast with dynamic memory.
stop bit. (1) A signal to a receiving mechanism to wait for the
next signal.
(2)
In a start-stop system, a signal following a
character or block that prepares the receiving device for the
reception of a subsequent character or block.
storage.
(1)
A storage device.
(2)
A device, or part of a device,
that can retain data.
(3)
The retention of data in a storage device.
(4)

symbol. ( 1) A conventional representation of a concept or a
representation of something by reason of relationship,
",--..... association, or convention.
(2)
A representation of something by
reason of relationship, association, or convention.
synchronization. The process of adjusting the corresponding
significant instants of two signals to obtain the desired phase
relationship between these instants.
Synchronous Data Link Control (SDLC). A protocol for
management of data transfer over a data link.
synchronous transmission.
(1)
Data transmission in which the time
of occurrence of each signal representing a bit is related to a fixed
time frame.
(2)
Data transmission in which the sending and
receiving devices are operating continuously at substantially the
same frequency and are maintained, by means of correction, in a
desired phase relationship.
syntax.
(1)
The relationship among characters or groups of
characters, independent of their meanings or the manner of their
