Chapter 4. Finding What You Need

Chapter 4. Finding What You Need

Finding what you need is easy, once you figure out the lingo. And you need to understand a little about the structure of the Net and the schemes used to describe things. People will refer to a Web page's URL, its domain name, and its IP address often interchangeably. This can be a little confusing at first. The terms are related, although they refer to slightly different aspects of the same thing. It might be confusing for someone from another planet to understand that we are our first names, last names, social security numbers, driver's license numbers, credit card numbers, and physical addresses—all meaning us. In a very basic way, the URL, the domain name and its levels, and the IP address all refer to the same thing—a specific Web page located on a server someplace on the Internet.

The biggest confusion is, perhaps, the fact that the World Wide Web (WWW) and the Internet are not the same thing. The WWW is all the resources and users on the Internet that are using the Hypertext Transfer Protocol (HTTP).
