Why would I want a home network anyway?
 
It used to be that when you had two computers at home, you needed two or more of everything like printers, modems, e-mail accounts, Internet connections and so on. With a home network you can share devices, programs and technology. The devices are all connected to each other over inexpensive components. You can share the more expensive of your devices like large hard drives, printers, scanners and of course .. Internet access. All of this requires a little more "management" than owning a single PC, but that is why you are becoming the home network pro.
