Whenever a user types a URL into the browser and presses the Enter key, his or her computer sends an HTTP request to the correct Webserver. The Webserver, developed to handle such requests, then sends the user the requested HTML page. Or to be entirely accurate, a Webserver can send HTML back to a browser dynamically and not necessarily in a page. Dynamic languages, such as PHP (PHP: Hypertext Processor), can generate HTML dynamically and not deal with it in a page.
