A small introduction to Ajax !!

Hi All,
Was working on the main consulting page for pragmaticworks.com , and I had to design a control , which will rotate and display images and bios of principle staff at PW. Just did some research to find a Devexpress Ajax control, which worked exactly in the manner I wanted it to work. So let me just begin with the defination of Ajax for all the newbies in the field of Development
"Ajax (shorthand for Asynchronous JavaScript and XML)^[1] is a group of interrelated web development methods used on the client-side to create interactive web applications" . Now this is the defination you will find if you google the word Ajax
Well in layman terms , I would describe it as a control in web application,which will give interactive features to a web application, without the use of reloading the whole page again . So for eg, if you look at the page here
( http://pragmaticworks.com/services/) ,you will find if you click Next for the bios of people at PW , you will see just the control loads itself to a new page, without loading  the whole page
This is what that makes web applications more user friendly and interesting . Similar to this is Jquery and javascript which are also interactive with the user
