Created by Bob Metcalfe at Xerox's Palo Alto Research Center, Ethernet offered a way to let everyone in the building use the first laser printer ever invented—which Xerox PARC also happened to have. (Some things never change: people on computer networks have been trying to make do with one shared printer ever since.) But over the decades, Ethernet has gotten faster, sturdier, and more powerful and remains an excellent choice for a network.

Note

Unless your house is pre-wired for Ethernet, with conveniently placed network jacks in each room, you probably won't want to use Ethernet to string together PCs spread across the far corners of your home. Wiring the innards of a whole house is a bit more than most people are willing to undertake, and stringing Ethernet cable down hallways can get old quickly. Therefore, the examples in this chapter assume that your computers are fairly close to one another—for example, clustered in a home office, or in neighboring rooms within reach of a 30-foot cable.

In this chapter, you'll learn about the hardware that makes Ethernet zoom, and you'll get step-by-step instructions for setting ...
