Question

what is MAC and why we need MAC?

Answer 1

Answer:

MAC

Explanation:

       

     MAC stands for Media Access Control. It is a unique identifier for network interfaces. It is used as a network address for most IEEE 802 network technologies. Sometimes it is known as the burned-in address (BIA) or the Ethernet hardware address (EHA).

      The MAC address is usually assigned by the manufacturer of a Network Interface Controller (NIC), and it is stored in the hardware. The NIC is a computer circuit card that allows a computer to connect to a network. During network communication the Address Resolution Protocol (ARP) for the Internet Protocol Version 4 (IPv4) or the Neighbor Discovery Protocol (NDP) for IPv6 translates the IP into a NIC.
