Your MAC address (or "hardware address") is a unique address that identifies your computer on the network. The MAC address is a part of your computer, so changing operating systems or upgrading it will not change your MAC address. The following is a tutorial on how to obtain your MAC address for various systems. The Ethernet cable must be plugged into both your computer and the wall port in order to complete these instructions.
