How Web Works?

Viewing a web page on the World Wide Web normally begins either by typing the URL of the page into a web browser, or by following a hypertext link to that page or resource. The first step, behind the scenes, is for the server-name part of the URL to be resolved into an IP address by the global, distributed Internet database known as the domain name system, or DNS. The browser then requests the resource by sending an HTTP request to the web server at that IP address. In the case of a typical web page, the HTML text is requested first and parsed by the browser, which then makes additional requests for graphics and any other files that form a part of the page in quick succession.
