What is AJAX?

AJAX (also know as Ajax) is shorthand for Asynchronous JavaScript and XML. The language is not technology in itself, but simply a term that refers to a group of languages (HTML, CSS, Javascript and XML).

The term Ajax was created by Jesse James Garrett, a co-founder of Adaptive Path. He said that he thought of the term when in the shower thinking of a word to represent the suite of technologies he was proposing to a client. Since the creation of the term many other programming languages have been used for implementing Ajax applications, for example VB, ASP, PHP and JSON.

Ajax is used by thousands of web sites all over the world to provide a more interactive user experience.
