WORLD WIDE WEB

        Popularly known as WWW, this is an information system on the Internet that allows documents to be connected to other documents by hypertext links, enabling the user to search for information by moving from one document to another. This WWW was found by Sir Tim Berners Lee, an English Engineer and a computer scientist.

       By October of 1990, Tim had written the three fundamental technologies that remain the foundation of today’s web (and which you may have seen appear on parts of your web browser):

• HTML: HyperText Markup Language. The markup (formatting) language for the web.
• URI: Uniform Resource Identifier. A kind of “address” that is unique and used to identify to each resource on the web. It is also commonly called a URL.
• HTTP: Hypertext Transfer Protocol. Allows for the retrieval of linked resources from across the web.

WEB PAGES

         This is a hypertext document connected to the WWW. It is a document that is suitable for the WWW. A web browser displays a web page on a monitor or mobile device. The web page is what displays, but the term also refers to a computer file, usually written in HTML or comparable markup language. 

WEBSITES

         This is a location connected to the internet that maintains one or more pages on the WWW. 

      Also, this is a collection of related webpages, including multimedia content, typically identified with a common domain name, and published on at least one web server.

WEB BROWSER

          This is a software application for retrieving, presenting and traversing information resources on the WWW. As a client/server model, the browser is the client run on a computer that contacts the Web server and requests information. The Web server sends the information back to the browser which displays the results on the computer or other Internet-enabled device that supports a browser.
