Detailed explanation-1: -It is a unique identifier assigned to every device on the network. It uniquely identifies the nodes on the network. It can be used to determine where a packet is coming from or going to.
Detailed explanation-2: -In the current internet era, most devices are connected physically with Ethernet cables or wirelessly with Wi-Fi. Both methods use MAC addresses to identify a device on the network. A MAC address is responsible for local identification and an IP address for global identification.
Detailed explanation-3: -The MAC is globally unique, so two devices can’t have the same MAC address. Each device’s MAC is represented in a hexadecimal format on each device, like this: 00:0a:45:2e:52:28. It’s a 12-digit number and is 48 bits long, also called a 6-byte hexadecimal number.
Detailed explanation-4: -A media access control address (MAC address) is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth.
