3. MAC Addressing

Short for Media Access Control address.

This is the unique identifier assigned to a network card or Wi-Fi adapter.

The code identifies the card and also the maker of that card.

It is a 48 bit binary number stored within the card hardware itself.

To make it a bit more people friendly the MAC address is usually quoted as a set of six hex number like this:

MAC address: 0A-14-FF-32-11-23

If you set up a WiFi one of the things you can do to improve security is to only allow devices with certain MAC addresses to connect to the network.
