To create a home network, the two main items you will need are a modem and a router. Depending on your specific computer hardware, there are a few other items you may need, but these are the two main components.
Modem
Example Cable ModemA modem is a device that allows a computer to send data over telephone or cable lines. It is the device that basically brings the Internet into the house. The type of Internet service you use -- dial-up, DSL, or cable, will determine the type of modem you use. If you are using DSL or cable Internet access, the modem is usually provided by your Internet Service Provider (ISP).
Router
Example RouterIn addition to a modem, you will need a router. A router is the device that is responsible for making sure the information that is being sent using the Internet makes it to the necessary destination. It allows two people to use the Internet at the same time without the pages being mixed up. The router directs messages so that each person is delivered the web page that he or she requested. This device is not supplied by your ISP, so you will need to purchase one if you decide to create a home network.
