A MAC address is a hardware identification number that uniquely identifies each device on a network. The full-form of MAC Address is ” Media Access Control Address ,” and yes it is not related at all with Apple Macintosh computers.
This MAC address is created in each network card, such as an Ethernet card or Wi-Fi card, and therefore cannot be changed.
Since millions of crores of networkable devices are present in the world today and every device needs a unique MAC address, a very wide range of possible addresses is needed. This is why, MAC addresses are created by six two-digit hexadecimal numbers, which are separated by colons.
For example, an Ethernet card may have a MAC address 00: 0d: 83: b1: c0: 8e . At the same time, you do not have to know about this address, because it is automatically identified by most networks.
