Serial Communication
Handshaking Signal
Synchronous, Iso-synchronous and Asynchronous Communication
• Synchronous: A byte or a frame of the data is transmitted or received at constant time interval with uniform phase differences.
• Bits of a data frame are sent in a fixed maximum time interval.
• In Iso-synchronous communication, the maximum time interval can be varied.
• Asynchronous: Bytes need not maintain a constant phase difference and are asynchronous,
• Bytes or frames can be sent at variable time intervals
