The MAC in MAC address stands for Media Access Control. This is a unique number that identifies the physical network hardware on your computer. Because of this, you may have three different MAC addresses, or more, on one computer, depending on how you are connecting to the internet. If you have the options of connecting via Ethernet controller, Wi-Fi, and telephone modem, each of these devices has a different MAC address. Although the syntax for MAC addresses has varied in the past, every current networking device now uses the IEEE 802 standard of six groups of two hexadecimal digits separated by dashes.
Finding the MAC address of your device depends on which type of computer you have and which operating system you are using.
