A Media Access Control address (MAC address) is also known as the physical address and is a unique identifier assigned to the network interface for communication. MAC addresses are generally used as a network address for most IEEE 802 network technologies (including Ethernet and WiFi). MAC addresses are used in the media access control protocol sub-layer of the OSI reference model.
