World Wide Web working principle

Viewing a Web page on the World Wide Web usually begins either by typing the URL of the page into a Web browser, or by next a hyperlink to that page or resource. The Web browser then initiates a series of communication messages, behind the scenes, in order to fetch and show it.

First, the server-name portion of the URL is resolved into an IP address using the global, dispersed Internet folder known as the domain name system, or DNS. This IP address is essential to contact and send data packet to the Web server.

The browser then requests the resource by distribution an HTTP request to the Web head waiter at that particular address. In the case of a typical Web page, the HTML text of the page is request first and parsed right away by the Web browser, which will then make additional requests for imagery and any other files that form a part of the page. Statistics measuring a website's status are usually based on the number of 'page views' or linked server 'hits', or file requests, which take put.

Having received the essential files from the Web server, the browser then render the page onto the screen as specified by its HTML, CSS, and other Web languages. Any images and other income are included to produce the on-screen Web sheet that the user sees.

Most Web pages will themselves contain hyperlinks to other connected pages and perhaps to downloads, source credentials, definition and other Web resources. Such a collection of useful, linked resources, unified via hypertext links, is what was dubbed a "web" of information. Making it accessible on the Internet shaped what Tim Berners-Lee first called the WorldWideWeb in 1990.
