goobes109: A NIC is a Network Interface Card, an ethernet port is the actual port that is on the card... the card or NIC could be PCI, could be a usb adapter or pcmcia for notebooks, etc. there are various kinds. I don't know all the kinds that would work in your desktop or laptop, why don't you just ask a guy in a store since you don't have a clue about it either? Once you get an ethernet port of some type on your computer just connect the crossover from that to the port on the back of the xbox then use the settings from my guide above.
