Home Office Networking Guide
Need to get a new home network up and running quickly?
Follow our step-by-step guide.
A computer network is an essential element of modern business, and it's increasingly indispensable in the home, too. A network lets your computer connect to the Web so that you can check e-mail, update a website, or teleconference. It also lets you communicate locally with other computers on the same local network. Creating a network is simple—all that's needed is to connect a computer to a router with an Ethernet cable. That's a very rudimentary setup, however. You'll need other components if you want to add multiple computers to your network, share files, stream multimedia, share a printer, or control which computers can access data on the network. And complexity increases if you decide that some links in your network will be made wirelessly.
