What is MAC Address –
he Media Access Control Address (MAC Address) of the computer is a unique identifier assigned to the network interface for communication with the data link layer of the network section.
In short a MAC address as a unique serial number assigned to the network. Any device that can connect to the internet has a network card. It can be your computer, smartphone, tablet even an internet TV. And if it has a network card then the network card has a unique MAC Address associated with it. Which is hard-coded into it, at time of manufacturing it.
So a MAC address is a string of numbers that are unique to each device. There have some reasons that two devices don’t have the same mac address. For instance, If I want to block any computer on my internet, then I merely block their MAC Address. Or if I want to track a device on my wi-fi then I will trace the device MAC Address. So because of MAC Address, we can identify which device is which.
Even though the MAC address is hardwired in your network card. You can still change MAC Address with the help of software. Now, one thing that I would like to make clear is- changing MAC Address is not illegal, but what you do with it may and may not.
