Synchronous transmission,
Definition of Synchronous transmission:
Data transfer method in which a continuous stream of data signals is accompanied by timing signals (generated by an electronic clock) to ensure that the transmitter and the receiver are in step (synchronized) with one another. The data is sent in blocks (called frames or packets) spaced by fixed time intervals. In contrast, asynchronous transmission works in spurts and must insert a start bit before each data character and a stop bit at its termination to inform the receiver where it begins and ends. Most network protocols (such as Ethernet, SONET, Token Ring) use synchronous transmission whereas asynchronous transmission is used commonly for communications over telephone lines.

Synchronous Transmission
Synchronization is achieved by sending synchronization symbols before the data. It does not use redundant information such as start and stop bits in asynchronous transmission to determine the start and end of characters, so it is faster and more efficient.
