What is AJAX: AJAX is an architecture and not a technology. AJAX stands for Asynchronous JavaScript And XML.

Ajax is a group of interrelated web development methods used on the client-side to create interactive web applications. With Ajax, web applications, you can send data, and retrieve data from, a server asynchronously without interfering with the display and behavior of the existing page. Data are usually retrieved using the XMLHttpRequest object. Despite the name, the use of XML is not needed, and the requests need not be asynchronous.

Like DHTML and LAMP, Ajax is not one technology, but a group of technologies. 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.
