How to Search the Web
How Does My Computer Know Where to Find a Web Page?
Every page on the Web has an Internet address, technically known as a Uniform Resource Locator, or URL. URLs identify the kind of document being read, the computer on which the page is stored, the location of the page on the computer, and the name of the file containing the page. The URL of this guide is http://www.bedfordstmartins.com/researchroom/websearch/index.asp:
- http:// is the protocol that your Web browser will use to access a particular kind of information on the Web. In this case, http indicates that the source uses hypertext transfer protocol. Other protocols include gopher (used to access Gopher sites), ftp (used to transfer files from one computer to another), and telnet (used to run programs on another computer on the Internet).
- www.bedfordstmartins.com is the name of the computer on which the page is stored. The .com extension on the end of the name of the computer indicates that the computer is in the Internet "domain" that supports commercial or business activity on the Internet. Other domains include .gov (government), .edu (education), .net (Internet infrastructure), .museum (museums), .biz (business), .info (a generic extension for any form of information), and .org (typically nonprofit organizations, but also other organizations that don't fit into the .gov, .com, .net, or .edu domains).
- /researchroom/websearch/ is the path (or the name of the folders containing the files for this guide).
- index.asp is the name of the file containing this guide's home page.
