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
• Stereos, TVs and game systems
• CD burners

The different network types use different hardware, but they all have the same essential components:

• More than one computer
• Hardware (such as a router) and software (either built in to the operating system or as a separate application) to coordinate the exchange of information
• A path for the information to follow from one computer to another
