AJAX works in the background on web pages to update a page without having to reload it.
Ajax is a client-side script that allows content on web pages to update according to a user’s action without the page having to be refreshed.
A stands for Asynchronous JavaScript and XML and is basically a technique that allows for the creation of faster and more interactive websites.
The script communicates to and from the server or database without the need for either a postback or page refresh.
