MAC addresses are an actual physical address that is hard-coded in the NIC that can never be changed. An example of how the MAC address looks like is 2F-6E-4D-3C-5A-1B. It knows where to drive the request in the MAC of your network interface.
At the hardware level, your network card keeps searching for the other MAC addresses for lining up on the same network. Here, your system requests your router which transmits it to the internet. On the browser, the web address you are looking for (let suppose is converted to an IP address (8.8.8.8) of that server. At the core of network connection, it is the MAC address of the network interface that helps in communicating with each other where the client request is passed down through various TCP/IP protocol layers. The MAC address in a device is assigned by the manufacturer of that device, but it is not that hard to change the address, which is commonly known as spoofing.

So, a MAC address is a 12-digit hex code having size 6 bytes and is used for uniquely identifying a host on the internet. It is also important to know that each NIC is associated with a unique MAC (Media Access Control) address which includes Wi-Fi cards and Ethernet cards also. As we all know a network interface card is a circuit board that is installed in our system so that we can connect to a network that eventually provides our machine a dedicated, full-time network connection.
