Data Link Layer: The 2nd layer of OSI Model

Data Link Layer

The Data Link layer is basically use for transfer frame data from one node (hop) to next adjacent node. It’s a second layer of OSI model. Basically it takes data packets from network layer put a header and trailer make frames and send it to physical layer.

Data Link Layer has two sub layers:
  1. Logical Link Control (LLC)
  2. Multiple Access Control (MAC)
Logical Link Control Logical link control use for design and procedure for communication between two adjacent nodes means node to node communication. Its functions are Framing, flow and error control and software implementation protocol.
