Computers, Telecommunications. of, pertaining to, or operating using fixed-time intervals controlled by a clock ( opposed to asynchronous ).
asynchronous communication is transmission of data without the use of an external
clock signal, where data can be transmitted intermittently rather than in a steady stream
.
Any timing required to recover data from the communication symbols is
encoded within the symbols. The most significant aspect of asynchronous
communications is variable bit rate, or that the transmitter and
receiver
clock generators do not have to be exactly synchronized.
