Ahh... Ajax.

Ajax is a relatively-recent programming model for web applications. The name is shorthand for Asynchronous JavaScript + XML, a phrase coined by Jesse James Garrett of Adaptive Path.

As defined by Garrett, Ajax is actually a combination of several well known technologies:

To cut a long story short, Ajax is usually used to enable changes in web pages to happen dynamically, without a full page refresh. From the user point of view, this provides an experience that is closer in model and performance to that of an interactive desktop application. 

There are plenty of articles about Ajax, but I would start from this two:

Note that Ajax is often stated as a requirement for a web application to be considered as part of the "Web 2.0" wave. Even worse, Ajax is sometimes considered as what makes an application "Web 2.0". Oh well...

Actually, the first commrecial application that could be called AJAX was Microsoft's Outlook Web Access (OWA). It's first version was created in 1998, so technically Microsoft was one of the first companies to use this technology, though at the time it wasn't named at all (certainly not AJAX).

Microsoft failed to realize the potential of this technology and it is clear in the products that followed OWA. In its development environmnet, ASP.NET, a framework to easily created AJAXian application only appeared as an addon for ASP.NET 2.0 and its still in development. The framework is named Atlas

AJAX is an acronym for Asynchronous JavaScript and XML. It's not a technology in itself, but a combination of technologies.

JavaScript provides client-side scripting, which means that scripts (programs) are run in the web browser instead of on the web server.

XML stores information in a text file, which is sent to the browser from the web server.
