Networking doesn't happen without hardware. First comes the networking adapter, hardware required in order to interface the PC with the network. Wire-based networks need wire, obviously. And all networks, wired or wireless, need hardware that makes up a central location, or hub, where all the wires are connected or wireless signals go to complete the network.

This figure illustrates a typical network layout. At the center of the network is a combination wireless base station and router. The router is connected to a broadband modem that’s connected to the Internet. The router is also wired into one PC and a printer. Two additional PCs access the base station by using wireless Internet.
