Data Link Protocol

Data Link protocols
• Asynchronous Protocols
• Not complex and inexpensive to implement
• Data unit is transmitted with no timing co-ordination between sender and receiver.
• Receiver does not know when data unit is sent- only recognizes the beginning and    ending of frame-accomplished by start and stop bit.
• Used primarily in modem, features start and stop bits and variable length gaps between    characters.
• Synchronous Protocols
