Networks

At its most basic, you can think of the World Wide Web as a special document delivery service that runs over the world's largest computer network, the Internet—the fabled global "electronic superhighway." Don't blanch at the word "network!" You use plenty of "networks" in your daily life: the telephone network, your cable TV network, your building's electrical network.

The Internet network

But the everyday network that most resembles the Internet is the street running right outside your building. You've got an address on that street. And it, and the other streets in your neighborhood or town, connect and eventually pour onto a wider street or highway. That highway connects to other neighborhoods or towns. And these highways eventually dump into higher-speed freeways that connect other main highways. And the freeways connect to airports and shipping ports that, in turn, cross the waters to connect to the freeways, highways (even donkey trails), and neighborhoods on other continents.

Think of each neighborhood or town as a network of streets. If you know the address you want, you can find a route to some other building clear across the world. Picture, then, the "highway network" as a network of networks. That's what the Internet is like.

Interestingly, you can thank the former Soviet Union for the Internet. The forerunner of today's commercial Internet actually started in the '60s as a U.S. Defense department project. The desire was to create a communications system that the Soviets couldn't easily bomb. Telephone networks were vulnerable because they relied on central switching points. Nuke the switch, and you close down large portions of the network.

The Rand Corporation came up with the decentralized network concept. Instead of a strict hub-and-spoke phone-switch arrangement, you had a fish net arrangement. Communication lines crisscrossed and intersected, and messages were switched—or "routed"—from point to point in many directions. If part of the "net" was destroyed, the "Net" (initially called ARPANET) could route messages around the disaster.

The Internet gradually widened to serve nonmilitary research, and finally, commercial use. The National Science Foundation initially provided the high-speed "freeway" portions of the Internet, but now, as it has opened to commercial use, most of the main freeways are commercially owned. It's a complicated ownership, but basically, big-time operators pay big bucks to telecommunications firms for a stretch of the highway, and then charge the rest of us by the minute or by the mile—so to speak.
