Media Access Control (MAC): Media Access Control (MAC) refers to the sublayer of the data link layer in the OSI model that is responsible for controlling how devices in a network gain access to the medium and permission to transmit data. A MAC address is a hardware identifier that uniquely identifies each device on a network. MAC addresses are typically 48 bits in length, expressed in hexadecimal format. In some cases, MAC addresses can also be 64 bits, particularly with modifications for use in IPv6 networking environments.
