Answer 1

Answer:

Media Access Control (MAC)

Explanation:

Every device that has a network interface card (NIC) contains a unique identifier called MAC address which differentiates it from other networking devices all over the world. It is also called a physical or hardware address. MAC addresses are integrated into the NIC of networking devices.

MAC addresses are a 12-digit hexadecimal number usually separated by a colon.

Note that a 12-digit hexadecimal implies also that it is a 6-byte (or 48-bit) number.

An example of a MAC address (in hexadecimal) is as follows;
