Detailed explanation-1: -A MAC address (media access control address) is a 12-digit hexadecimal number assigned to each device connected to the network. Primarily specified as a unique identifier during device manufacturing, the MAC address is often found on a device’s network interface card (NIC).
Detailed explanation-2: -In IEEE 802 LAN/MAN standards, the medium access control (MAC, also called media access control) sublayer is the layer that controls the hardware responsible for interaction with the wired, optical or wireless transmission medium.
Detailed explanation-3: -A media access control address (MAC address) is a unique identifier for an Ethernet or network adapter over a network. It distinguishes different network interfaces and is used for a number of network technologies, particularly most IEEE 802 networks, including Ethernet.
Detailed explanation-4: -MAC addresses are implemented by software. A NIC only needs a MAC address if connected to a WAN.
