How Does The World Wide Web Work ?
The World Wide Web is a large network of interconnected web pages containing information and data about everything known (and even unknown) to man. This useful and invaluable system was created by Tim Berners-Lee, in association with CERN, Switzerland in the year, 1990, and today it has become an inseparable part of our lives. |
Before trying to understand the functional aspects of the Web, one must not confuse it with the Internet. It is possible because the Net is closely connected to the Web, in the sense that the latter works only with the help of the former. The Web, or WWW, as it is abbreviated, is a database of huge number of documents and other types of resources, each of which are interlinked with the aid of URLs and hyperlinks. To view each web page on the computer, one must be connected to the internet first and then the specific URL should be typed on the web browser or a hyperlink must be clicked on one web page to navigate to the other. Then the web browser gives rise to numerous communication messages which enables us to access each of the pages.
At this point, the concept of Hypertext Transfer Protocol or HTTP comes in. this is used to access the Web. The browser then asks the server for the specific web page, which is then displayed through HTML, or Hypertext Markup Language, CSS, or Cascading Style Sheets, or other available page composition languages. The web pages carrying the necessary information may come in the form of text, image or even video.
