XML is typically used as the format to receive server data. Though, any format can be used such as plain text. Natural and intuitive user interaction is another vital feature of Ajax. You don’t need to click, as mouse movement is enough to trigger events. This web browser technology is independent of web server software. Users can keep using the application when the information of the client program requests from the server in the background.
