You can also share your Internet connection using a computer modem or even a high-speed cable modem between the two systems. Internet sharing programs will also allow two or more users to use the Internet connection simultaneously. This can end the arguing over who gets the computer that's connected to the Internet. The Home Computer Network industry is starting to gain momentum and is also developing various standards and technologies to support Home Networking. Right now there are three methods employed in connecting your computers together in a Home Network.
Wired systems are the most traditional and fastest method available.
The wired Ethernet system typically consists of network adapter cards for the PCs, CAT5 cabling, and a network hub. The wired CAT5 system can often be the least expensive way of getting started. The major drawback to wired systems is that you have to run wires. This is not a big problem when the computers are close together, but may require professional installation between rooms on other floors of the house or through walls. An alternative system that is gaining popularity is the Phone Line Network.
