"The World Wide Web – normally abbreviated to "the Web" or sometimes "the Net" - is a vast collection of electronic documents each composed of a linked set of pages written in HTML. The documents are stored in files on many thousands of computers that are distributed around the global Internet" (HALSALL 2005, p. 568)

"A Web Page is a "page" of the WWW, usually in HTML / XHTML format and with hypertext links to enable navigation from one page or section to another." (WIKIPEDIA)
A Web Page contains all the information necessary both to display the contents of the page – text, images, and so on – on the screen of the user machine and also the links that lead to other Web Pages. (HALSALL 2005, p. 570)

A Web Browser is a software application that runs on the user machine and enables the user to display and interact with Web Pages hosted by Web Servers. "A Web browser locates and fetches each requested page and, by interpreting the formatting commands that the page contains, the page contents are displayed." (HALSALL 2005, p. 570) There are a number of browser programs available such as Mozilla Firefox, Opera, Internet Explorer, etc.

A Web Server is a computer permanently connected to the Internet on which Web sites are stored and accessed. (Kudos Webdesign) The Web Server manages requests from the browser and delivers HTML documents and files in response using HTTP. (PC Magazine)

HTTP is the protocol used by a browser program to communicate with a server program over the Internet and is based on IP and TCP. (HALSALL 2005, p. 569)

"A URL comprises the name of the file and the location of the server on the Internet where the file is stored." (HALSALL 2005, p. 569)
