synchronous transmission

A form of transmission in which blocks of data are sent at strictly timed intervals. Because

the timing is uniform, no start or stop bits are required. Compare asynchronous transmis-

sion.

Some mainframes only support synchronous communications unless their owners have

installed a synchronous adapter and appropriate software.
