MAC address

A MAC address is the equivalent to the serial number of a network card. Each MAC address is unique, and so identifies the network card you have installed in your computer.

Your computer's MAC address in conjunction with your IP address is used to provide you with the most secure service ITS can offer.

Sometimes we need to know the laptop MAC address. Fox example, you want your laptop connect to a wireless network which is MAC address authentication needed. So you should get MAC address of your laptop first of all and here's how.

Click on 'Run..'
Type 'cmd' without quotes and press Enter.

Your MAC Address is listed under 'Physical Address' as a series of 6 groups of two digits, letters and numbers, separated by dashes, such as in the image below. Make sure you get the physical address of the correct network adapter - usually there are several listed.
