Stands for “Media Access Control ,” and no, it is not related Apple Macintosh computers. A MAC address is a identification number that uniquely identifies each device on a . The MAC address is manufactured into every network card, such as an  card or Wi-Fi card, and therefore cannot be changed.

Because there are millions of networkable devices in existence, and each device needs to have a unique MAC address, there must be a very wide range of possible addresses. For this reason, MAC addresses are made up of six two-digit  numbers, separated by colons. For example, an Ethernet card may have a MAC address of 00:0d:83:b1:0:8e. Fortunately, you do not need to know this address, since it is automatically recognized by most networks.
