Network Identifiers

What is Network Identifiers ?

       Once a network has been setup, the nodes can communicate among themselves. But for proper communication, the node must be uniquely identifiable. If a node sends some information to another node that means it is mandatory that the both nodes are uniquely identifiable.

 The MAC address of a NIC card is permanent and never changes.This addresses is a 12-digit hexadecimal(48 bit) number. By convention, MAC addresses are usually written in one of the following two formats.
                MM:MM:MM:SS:SS:SS
                MM-MM-MM-SS-SS-SS

     The first half (MM-MM-MM /MM:MM:MM) of a MAC address contains the ID number of the adapter manufacturer. And the second half (SS-SS-SS/SS:SS:SS) of a MAC address represents the serial number assigned to the adapter (NIC) by its manufacturer. 

Another network Identifier is IP address. IP stands for Internet Protocol. As like MAC address IP address also a network Identifier.
