AJAX and Its History
AJAX is a group of interrelated web development techniques used on the client-side to create interactive web applications. With Ajax, web applications can retrieve data from the server in the background without interfering with the display and behavior of the existing page. The use of Ajax techniques has led to an increase in interactive or dynamic interfaces on web pages. Most of the times the data is retrieved using XML HttpRequest object.
The term "Ajax" was given in 2005 by Jesse James
