Question

Synchronous protocols

• A. Transmit characters one at a time
• B. Allow faster transmission than asynchronous protocols
• C. Are generally used by personal computers
• D. All of the above

Answer 1

Answer: (B)

Allow faster transmission than asynchronous protocols

Synchronous protocols allow faster transmission than asynchronous protocols. Synchronous protocols:- A serial communication protocol in which "data is sent in a continuous stream at constant rate".

Synchronous communication requires that the clocks in the transmitting and receiving devices are synchronized– running at the same rate – so the receiver can sample the signal at the same time intervals used by the transmitter.

Asynchronous protocol:- In telecommunication signaling within a network or between networks, an asynchronous signal is one that is transmitted at a different clock rate than another signal.
