Yes, every NIC has a pre-assigned unique MAC address burned into a chip on the card. You can override this address and make it something else if you choose to. The MAC address is only used to communicate to the next device in the local network, like your router or cable modem or another PC.

The MAC address is part of the NIC card.

A MAC address is burned(built in) to the chip for every network interface on a computer. All MACs should be unique. The first three sets of a MAC indicates what company the interface was made by. The last three sets are a random unique set not used by that company before.

All NIC cards have their own MAC address built in

Yes. You're MAC address is assigned permanently...not like an IP address

yes, and you can not change it. it is burned into the card kind of like the serial number on, say, a car. that is why it is better to block someone using their MAC address instead of their IP address. you can always re-new your IP but the MAC addie is there forever. the only way to change it is to buy a new network card.
