Ajax is a group of web development technologies that are used on the client side to create more dynamic web pages by allowing the small amount of data to be sent from the client to the server in real time without the need to reload the entire web page.
Ajax is a client-side script that communicates to and from a server/database without the need for a postback or a complete page refresh. it is a part of web page.
Basically this is what AJAX does for your application
* Update a web page without reloading the page
* Request data from a server - after the page has loaded
* Receive data from a server - after the page has loaded
* Send data to a server - in the background
Ajax is nothing but Asynchronous JavaScript and XML. IT works at client side as normal JavaScript does. The driving force behind the usage of Ajax technology is that it makes communication or exchanges data to and from server & database without making any page refresh.
