Read MoreThe Data Link Layer of OSI Model
The data link layer (Layer 2) converts the raw transmission facility provided by the physical layer to a reliable and error-free link.The main functions of the data link layer are as follows −It breaks up the stream of bits into data frames having sizes from a few hundred to a few thousand bytes.It ensures distribution of the frames to the different systems. For this, it adds a header to the frame containing the address of the sender and the receiver.In case of reliable connection, this layer ensures that the receiver sends an acknowledgement frame.
