in other words

  • You enter, say, http://website.com into your browser’s address bar.
  • Your browser looks up the IP address for website.com.
  • Your browser issues a request for the home page at website.com.
  • The request crosses the Internet and arrives at the web server on which the files that make up website.com are stored.
  • The web server, having received the request, looks for the requested page on its hard drive.
  • If the server contains scripts that request (say) user data from a database, they go find the database and fetch the requested data.
  • The server retrieves the web page and any requested data and returns it to the browser, which displays the web page.
