Home Networking:
Once, home networks were primarily the realm of technophiles -- most families either didn't need or couldn't afford more than one computer. But now, in addition to using computers for e-mail, people use them for schoolwork, shopping, instant messaging, downloading music and videos, and playing games. For many families, one computer is no longer enough to go around. In a household with multiple computers, a home network often becomes a necessity rather than a technical toy.
A home network is simply a method of allowing computers to communicate with one another. If you have two or more computers in your home, a network can let them share: 
Files and documents
An Internet connection
Printers, print servers and scanners
Stereow, TVs and game systems
CD burners
