How the Web Works

The World Wide Web isn’t a particular place on the Internet, nor is it a particular computer or something that you can “log into.” Instead, the best way to describe the Web is as a service on the Internet. Using certain protocols, computers that are designated as Web server computers—because they’re connected to the Internet and run Web server software—can respond to requests from client computers running Web browser software.

Note

It’s easy to confuse the Internet and the Web, but they are different. The Internet is the global network of wires, servers, and protocols that enables millions of computers to communicate with one another. The Web is a service that’s made available over the Internet. It’s just one means of accessing information and communicating via the Internet, along with email, Internet chat, file transfer, and others.
