A media access control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
To find the MAC address in your computer (Windows 7), all you have to do is
1) Click on Start , type in “cmd”
2) Select Command Prompt.
3) In the new black windows that appears, type in getmac and hit Enter.
The command will show all the TCP/IP connections in the computer. The result of the command will give the MAC address of the computer.
