AJAX
AJAX stands for Asynchronous javascript and xml.
While not a technology in itself, AJAX is a term coined in 2005 by Jesse James Garrett, that describes a "new" approach to using a number of existing technologies together, including: HTML/XHTML, CSS, JavaScript, the DOM, XML, XSLT, and most importantly the XMLHttpRequest object. AJAX uses the XMLHttpRequest (abbreviated XHR) API to manage HTTP requests from inside the code.
When these technologies are combined in the AJAX model, web applications are able to make quick, incremental updates to the user interface without reloading the entire browser page. This makes the application faster and more responsive to user actions.
This communication is performed by javascript code in the browser. Originally, it was anticipated that the data would be encoded in xml form, hence the acronym AJAX. However the term is now used for all browser/server interaction of this type, even when XML is not used.
Although the X in AJAX stands for XML, JSON (JavaScript Object Notation) is used more than XML nowadays because of its many advantages, including the availability of native methods to handle it, its lightness (compared to XML) and also being a strict subset of JavaScript. Both JSON and XML can be used for packaging information in the AJAX model.
XMLHttpRequest is the main method of interacting between the server and the client; it is supported by all modern browsers. Early versions of Internet Explorer (IE 5 and 6) don't support the native XHR API, although they do support an ActiveX API which has most of the capabilities of XHR (an example of this is new ActiveXObject("MSXML2.XMLHTTP.3.0")).
