One of the great technological inventions is the WWW. Really, it has revolutionized the way we live and the way we do our day to day works. Its knowledge is of even more greater magnitude. To, just see, it will look like magic but it has taken many people's hard work and dedication in actually bringing this forth to this world. If WWW would not have existed, then we still would have not called this age modern as we call it now. Truly, it is worthy of never to be completed praises and accolades. WWW's full form is the World Wide Web. It is a system of hypertext, interconnected documents which can be accessed through the internet. What a user does is, he goes through the web pages which are the pages on the display that may consist images, text, videos and other multimedia and steers between them with the help of hyperlinks. Sir Tim Berners Lee who was from the United Kingdom and Robert Caillau who was from Belgium invented this World Wide Web in the year 1989. They worked together at CERN in Geneva which is in Switzerland. Ever since, Sir Tim burners Lee has managed to play an important role in directing the expansion of the web standards. One of the major web standards is the markup language. In that the web pages are composed. In recent years, he has given air to his vision of semantic web. If you want to view a page on the web, then either you can type the URL of that page or you can follow a hypertext link or some resource to that page. Domain name system is the global distributed internet database. It is also known as DNS. It plays an important role by helping the server name part of the URL to be resolved in to an IP address. Then, at that IP address, the browser requests the link by transmitting an HTTP request. The browser first requests an HTML text and then parses it. After that, it makes the request for graphics and other files that are a major part of the page in quick succession. These additional requests of the files are critical because they give air to the difference which exists between a single page view and an associated number of server hits, thus increasing web site popularity statistics across the globe. As described by the HTML programs, CSS and other essential files incorporating the images and other resources necessary, the browser then finally provide the page. Thus, the user is able to view the on screen page, thus bringing immense satisfaction and happiness to the viewer. So, it takes a long procedure and hard work to bring out the one page that user sees. It is not that easy. HTML which is known as Hyper Text Mark Up Language is a major program which helps the text changes, image transformations, videos, songs to be played and all the other major magic like things that happen over a web page on the internet. For example, in a web page, it changes the color of the text, brings various images on the web page, and brings a song to be played on a web page and various other great things. So, it looks like magic to the viewer. Another major programming language is the JAVA. Mostly, it is made use in creating software. For example, the life changing Yahoo Messenger has been made by the help of JAVA because of which we can chat with our distant friends and even talk to them through Yahoo Messenger voice Chat. Thus, WWW is a revolution which happened.
