In short, Ajax is the method of communicating from a page to a webserver, using JavaScript, without leaving the website. AJAX lets you send the server only important information, not the entire page. So only valuable client-side data is routed to the server-side. It's making your application interactive and quicker. There are many web applications that are running on the web, using ajax technology such as Gmail, Facebook, twitter, google map, youtube, etc. If you know more about ajax and learn then you visit our ajax tutorial.
