What is a MAC address?

According to webopedia.internet.com, it is:

"Short for Media Access Control address, a hardware address that uniquely identifies each node of a network"

MAC addresses are twelve characters, usually appearing in sets of two. They usually begin with a 00 and values can range from 0-9 and A-F.

MAC addresses are sometimes printed on the card itself and usually in the materials provided by the manufacturer.

You can also use software to discover it.
