Answer from AI

In the OSI model, the second layer is the Data Link Layer. It is responsible for establishing, maintaining, and terminating connections between nodes within the same physical network.

Main functions of the Data Link Layer:

  • Framing bits received from the physical layer into frames.
  • Managing access to the transmission medium (e.g., CSMA/CD in Ethernet).
  • Error detection and correction.
  • Flow control between neighboring nodes.

Examples of Data Link Layer protocols: Ethernet, PPP, HDLC.
