Stands for "Uniform Resource Locator." A URL is the address of a specific Web site or file on the Internet. It cannot have spaces or certain other characters and uses forward slashes to denote different directories. Some examples of URLs are http://www.cnet.com/, http://web.mit.edu/, and ftp://info.apple.com/. As you can see, not all URLs begin with "http". The first part of a URL indicates what kind of resource it is addressing. Here is a list of the different resource prefixes:
- http - a hypertext directory or document (such as a Web page)
- ftp - a directory of files or an actual file available to download
- gopher - a gopher document or menu
- telnet - a Unix-based computer system that you can log into
- news - a newsgroup
- WAIS - a database or document on a Wide Area Information Search database
- file - a file located on your hard drive or some other local drive
