Explain three functions of data link layer

---

Specific functions of the data link layer include the following,
-Framing: The data link layer receives the stream of bits from the network layer divides into manageable data units called frames.
-Physical addressing: If frames are to be distributed to different stations on the network. To define the physical address of the sender (source address) and/or receiver (destination address) of the frame, the DLL adds a header to the frame.
If the frame is to be sent for a system outside the sender's network. The receiver's address means the address of the device that connects one network to another.
