WHAT IS AJAX
AJAX means Asynchronous JavaScript and XML, Ajax is a web development technique used for creating interactive web applications. It is a new way to use existing standards. Ajax is a cross-platform technique that can be used on a variety of operating systems, computer architectures, and Web browsers due to its JavaScript and XML foundation.
Ajax exchanges data with a server, and updates parts of a web page – without reloading the whole page. It uses both client-side scripting and server-side scripting. Ajax is a group of technologies, using HTML and CSS technologies to mark up and style information. JavaScript is used to display and allow the user to interact with the information presented. The combination of JavaScript and the XMLHttpRequest object offer a way for exchanging data asynchronously between browser and server to avoid full page reloads.
The main goal of this technique is exchanging small amounts of data with the server behind the scenes. Web pages become more responsive because the user does not need to reload the whole page each time a change is necessary. This inlarges the web page’s interactivity, speed, functionality, and usability greatly.
