What is a MAC address?

What will be an ideal response?


The MAC address is a hardware address that uniquely identifies each node of a network. Other names for the MAC address are vendor address, vendor ID, NIC address, Ethernet address, and physical address.

The MAC address is a unique 48-bit number that is "burned" into the network interface adapter when it is manufactured. This number consists of two parts: a 24-bit organizationally unique identifier (OUI), sometimes called a "company ID," which references the company that produced the adapter, and a 24-bit individual address block (IAB), which uniquely identifies the card itself.
