Consequently, each different type of network medium requires a different MAC layer. The MAC layer interfaces directly with the network medium. Technically, In IEEE ( Institute of Electrical and Electronics Engineers) 802 networks, the Data Link Control (DLC) layer of the OSI Reference Model is divided into two sub-layers they are, MAC Address is widely used to identify a device or a computer in a network as it is difficult to change or spoof MAC Address. MAC (Media Access Control) address is a hardware address that uniquely identifies each node of a network.
