AXJAX is a term that represents a group of javascript based code that creates interactivity for the user and allows for content arrangement that does not require reloading a page.

Mootools and scriptaculous are two sites that are resources for this type of code, lightbox would be another for image gallery.

Ajax stands for Asynchronous Javascript And XML. It is a web development technique used for creating interactive web applications and the logical next step in the services-oriented architecture revolution. With Ajax, user interfaces from within the browser can use web services as their data source to store and retrieve information.

It's Javascript + XML code used together to allow for asynchronous data transfer and more interactive web sites without needing to reload web pages. Think DHTML but with XML and more server end capabilities. I like Wikipedia's entry which is at - http://en.wikipedia.org/wiki/AJAX(Jade your Wiki link is the same one but a bit broken)

It's also the newest technology on my pile of "sexy development stuff to learn".

Ajax is usually used to refer to a set of objects in javascript that make it possible to communicate with server-side scripts/technology. A simple example, might be a page that posts the date. Without AJAX the page would need to reload to get that information from the server. However, using AJAX a a request is sent for a server-side script to be parsed and that information is returned in an object. The information within that object can be accessed and added to the page without needing to reload the page. Before you start learning AJAX you should be fairly familiar with a server-side language(php, asp) and javascript. Lastly, AJAX should only be used as an enhancement. A site should be able to function regardless if "AJAX" object initalization fails or javascript is turned off in the browser. For example, an handler for links within site cancels their default action and a xmlhttprequest object fails to be created. Than if you haven't taken the proper precautions when using the technology the links will fail to navigate anywhere. Its best to make certain that the technology is available before canceling the default action of links. This way if object initialization fails event listeners for the links won't be added – thus the page will function as normal, but the AJAX enhancement won't be available. However, the site will still function properly.
