Be it notebook or desktop PC, nothing talks without a Network Interface Card (NIC). As with virtually every expansion card in a PC, the NIC needs an I/O address and IRQ to interface. While today, Plug and Play makes that assignment automagic; one area that may need your manual attention is the driver. Updating drivers when upgrading an Operating System with a Service Pak is common.
As you may have figured out by now it is the actual NIC that gets the IP address that we discussed earlier in this chapter. However, the IP address gets a close association with an identity that is ingrained into the cards creation as part of creating a network.
