What is World Wide Web and what makes it works? 

The WWW incorporates all of the internet services above and much m9ore. You can receive documents, view images, animations, and videos, listen to sound files, speak and hear voice, and view programs that run on practically on any software in the world, providing your computer has the hardware and software to do these things. When you log onto the internet using a browser (e.g., Internet Explorer, Fire fox, Mozilla, Netscape, Opera, Safari), you are viewing documents on the World Wide Web. The basic foundation on which the WWW function is the programming language called HTML. It is HTML and other programming imbedded within HTML that makes possible hypertext. Hypertext links, which are areas in a page or buttons or graphics on which you can click your mouse button to retrieve another document into your computer. This “click ability” using Hypertext links is the feature, which is unique and evolutionary about the Web. How do hypertext links work? Every documents or file or site or movie or sound file or anything you find on the Web has a unique URL (uniform resource locator) that identifies what computer the things is or, where it is within that computer, and its specific file name. (More explanation on the structure of URLs.).Every Hpertext link on every web page in the world contains one of the URLs. When you click on a link of any kind on a webpage, you send a request to retrieve the unique document on some computers in the world that is uniquely identified by that URL. URLs are like addresses of webpages. A whole cluster of internationally accepted standards (such as TCP/IP and HTML) make possible this global information retrieval phenomenon that transcends all political and language boundaries.
