It is a unique string of letters and numbers (actually a single number in hexidecimal) that identifies your computer on a network. No two devices on the same network will ever have the same MAC address, so routers and other computers can know who everyone is and talk to them accordingly. A BN cannot get the instructions from a router that were intended for a PC, but that will never happen because the router knows that the BN has a specific MAC address and so will never mix it up with any other machine.

Have a great day,
