Ajax (An Introduction)



AJAX Introduction

AJAX stands for Asynchronous JavaScript and XML.
If you are new to web development than, a question can arise in your mind that why do we require AJAX when we already have HTML, JavaScripts etc... Now let me clarify you, suppose you are having a web page with server side scripting (that can be in ASP, JSP, PHP), in that case to make little change we will have to reload whole page (Whole page will be rendered).
Whereas AJAX allows you to reload the only required part of the page which is required changes. So we can say AJAX allows partial rendering of the page.
