The Data Link Layer is the second layer in the OSI model, above the Physical Layer, which ensures that the error-free data is transferred between the adjacent nodes in the network. It breaks the datagrams passed down by the above layers and convert them into frames ready for transfer. This is called Framing.
In this “Data Link Layer - Data Communication and Computer Network” you will learn about following topics:
- Introduction of Data Link Layer
- Framing
- Character Count
- Starting and Ending Characters, With Character Stuffing
- Starting and Ending Flags, With Bit Stuffing
- Physical Layer Coding Violations
- Basics of Error Detection and Correction
- Process of Error Detection
- Error-Detecting Codes
- Parity Check
- Vertical Redundancy Checksum
- Longitudinal Redundancy Checksum
- Checksum
- Cyclic Redundancy Check
- Error-Correcting Codes
- Flow Control
- Retransmission Strategies
- Stop and Wait
- Go-Back-N ARQ
- Selective Repeat ARQ
- Protocol Pipelining
- Sliding Window Protocols
