A network is simply two or more computers physically connected together. Networks are typically created so that one computer can use a device, like a printer or scanner, that is connected to different computer. A network in a home can also be used to share a single Internet connection among several computers.
Family members can also easily share files between computers on the network.
The biggest difference between a home network and a traditional business network is the complexity of the products required to make it happen. Hardware and software components have been developed to create home networking features that are easy for consumers to understand and use. You can set up your home network using the existing in-home phone wiring in your house or by using a Category 5 Ethernet cable and hub. Multiple computers can share one printer, modem, scanner, etc. Networked computers can share files and applications.
