MAC Address

The MAC address is the six byte long hardware address that uniquely identifies a device in the network. It hard-coded onto a chip  by the manufacturer and cannot be manipulated. Every piece of network hardware has a unique identifying number, thus, no two MAC addresses are alike.

NOTE: In the picture above, the MAC address is visible under the bar-code on the device.

NOTE: There is a whole colum of varied MAC Addresses for the diffrent computer systems available.
