Happening at the same time; simultaneous.

A process where data is transmitted as a constant transmission stream.

Refers to data transmission wherein the transmitter and receiver are synchronized and data is sent at a fixed rate. Synchronous transmission eliminates the need for start and stop bits when compared to asynchronous transmission, and is therefore more efficient. Most high-speed data circuits, from ISDN to T3, are synchronous.

when applied to computer-mediated communication, this relates to software that supports discussion between users of the same system at the same time. Chat rooms, MUDs and MOOs are all examples.

detection This feature is found on the Sony IFC-SW07 , SW1000T and Grundig Satellite 800. It is a circuit that replaces the carrier in a received AM signal with with an internally generated replacement to reduce the effects of fading.

The primary circuit board in a PC that contains most of the basic components of the system.

Operating at the same speed, all circuits in a synchronous network are constrained to operate at their nominal rates with no significant variation.

Two or more signals in step or in phase.

A synchronous operation or function does not return control to its initiator until it has completed the requested operation or function.

A mode of operation where an end system must wait for the answer to an operation before asking for another one to be performed.

A type of teletypewriter operation where both transmitter and receiver operate continuously.

A property of a function that begins an operation and returns only when the operation is complete.
