Wired Networks

Ethernet and wireless networks each have advantages and disadvantages; depending on your needs, one may serve you better than the other. Wired networks provide users with plenty of security and the ability to move lots of data very quickly. Wired networks are faster than wireless networks, and they can be very affordable. However, the cost of Ethernet cable can add up -- the more computers on your network and the farther apart they are, the more expensive your network will be. In addition, unless you're building a new house and installing Ethernet cable in the walls, you'll be able to see the cables running from place to place around your home.

If you plan to connect only two computers, all you'll need is a network interface card (NIC) in each computer and a cable to run between them. The most commonly used cable is Category 5 Unshielded Twisted Pair (UTP) cable. If you want to connect several computers or other devices, you'll need an additional piece of equipment: an Ethernet router. You'll also need a cable to connect each computer or device to the router.

Once you have all of your equipment, all you need to do is install it and configure your computers so they can talk to one another. Exactly what you need to do depends on the type of network and your existing hardware. For example, if your computers came with network cards already installed, all you'll need to do is buy a router and cables and configure your computers to use them. Regardless of which type you select, the routers, adapters and other hardware you buy should come with complete setup instructions.

The steps you'll need to take to configure your computers will also vary based on your hardware and your operating system. Check out these links for more detail on how to get your computers talking to one another:

Nervous about Networking?
Most people who have a basic familiarity with computers can set up a network without much help. But the idea of installing cards and making connections makes some people nervous. Many Internet service providers (ISPs) offer home networking packages. For a monthly fee (and sometimes an initial setup cost), the ISP will provide you with the hardware and support you need to build and maintain your network.
