Explanation:
Media Access Control address (MAC address) is a unique identifier assigned to most network

adapters or network interface cards (NICs) by the manufacturer for identification, and used in the
Media Access Control protocol sub-layer. If assigned by the manufacturer, a MAC address usually
encodes the manufacturer’s registered identification number. It may also be known as an Ethernet
Hardware Address (EHA), hardware address, adapter address, or physical address.
