What is AJAX?

AJAX is an acronym for Asynchronous JavaScript And XML. AJAX is not a new programming language, but simply a new technique for creating better, faster, and more interactive web applications. AJAX uses JavaScript to send and receive data between a web browser and a web server. The AJAX technique makes web pages more responsive by exchanging data with the web server behind the scenes, instead of reloading an entire web page each time a user makes a change. AJAX Is A Browser Technology AJAX is a technology that runs in your browser. It uses asynchronous data transfer (HTTP requests) between the browser and the web server, allowing web pages to request small bits of information from the server instead of whole pages. The technology makes Internet applications smaller, faster and more user friendly. lamp AJAX is a web browser technology independent of web server software.

Ajax is the technique where our browser creates the http request and sends to server without knowing to user. Ajax is use for making faster and reliable web application because it removes overhead of requesting page manually. Ajax is a smarter way to use client side scripting and getting the response from server without refreshing page.
