Synchronous Asynchronous Transfer Mode ATM is related to message transfer from one to other means sender to receiver. Synchronous vs Asynchronous Transfer Mode ATM differs from clock signal, data transfer rate and data size.
Following are the key point’s focuses under difference between synchronous and asynchronous transfer mode ATM.
|S.N||Synchronous Transfer Mode||Asynchronous Transfer Mode|
|1||Sender and receiver use the same clock signal||Sender provides synchronization signal to the receiver before transfer of each message|
|2||Synchronous means “at the same time”||Asynchronous means “at regular intervals”|
|3||Support high data transfer rate||Support low data transfer rate|
|4||Need clock signal between sender and receiver||No need of clock signal between sender and receiver|
|5||There are no start, stop bit and gap||There are start, stop bit and gap|
|6||This is serial in nature||This is periodic in nature|
|7||Signals are not in agreed pattern||Signals are sent in an agreed pattern|
|8||Data format consist large and variable size data||Data format consist short and fixed cells|
|9||It is used when large block of data at relatively higher bit rates||It is used when data to be transmitted at random interval|
|10||It is also known as High Level Data Link Control or HDLC||It is refereed to as Quality of Service parameter|
