it is a technique, rather than a framework.it allows web pages to behave less like flat document and more like dynamic website apps that users might expect from their desktop environments.ajax techniques can be used for all recent browsers(including Internet Explorer and Netscape/Mozilla, chrome, etc.)
The main purpose of using Ajax is to enable web applications to extract data from the various servers in an asynchronous manner; means that the web applications retrieve information from the server in the background without requiring the user to refresh the web page.
Ajax is the technique of exchanging data with a server and update parts of a web page without reloading the whole page. Ajax technology is based on the HTTP request, an API that can be used with most of the web browser scripting languages. Ajax is used mainly to build a fast, dynamic website but also to save resources.
