Ajax uses a combination of HTML and CSS to mark up and style information. The DOM is accessed with javascript to dynamically display, and to allow the user to interact with the information presented. javascript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads.

Ajax, shorthand for Asynchronous javascript and XML, is a set of technologies that allows you to create Web applications that don't need to refresh Web pages in the browser. You can operate behind the scenes, connecting to the server, uploading and downloading data, and display the results in the browser using dynamic HTML. Using Ajax gives your Web pages the feel of a desktop application-the whole display will no longer flash when you click a button.
