Detailed explanation-1: -A MAC address is made up of 48 bits. And those 48 bits, they’re divided into two different groupings, 24 bits each. The first 24 bits, those are unique to the specific manufacturer or vendor. Those bits are called the OUI, or organizationally unique identifier.
Detailed explanation-2: -Both MAC addresses and IP addresses serve the same purpose, which is to identify a device on a network. While the MAC address identifies the physical address of a device on the same local network, the IP address identifies the device globally or through its internet address.
Detailed explanation-3: -The MAC address is a hardware identifier that uniquely identifies each device on a network. If the device, for example a laptop, has both a wired (Ethernet) and wireless (Wi-Fi address) connection then there will be one wired MAC address for the wired connection, and a second wireless MAC for the wireless connection.
