AJAX stands for Asynchronous JavaScript and XML. It is not a programming language or tool but it is a concept. Ajax is a client side script that communicates to and from a server without the need of a postback or a whole web page refresh. The most appropriate definition for Ajax is "the technique of exchanging data with a server and updating components of a web page – without reloading the entire web page". Ajax allows web pages to update asynchronously by exchanging data with a web server behind the scenes. Which means it is possible to update a web page, without reloading the entire web page.

Ajax can use anywhere in a web application where a small amount of information is saved or retrieved from the server without posting back the whole page. A good example of this is data validation on save actions. Another example is to alternate the values in a drop down list based on different inputs, like states and college list's boxes. Using Ajax, a developer can do the following things

  • Update a web page without reloading

  • Request data from the server - after the page has loaded

  • Receive data from server – after page has loaded

  • Receive data from the server – after the page has loaded

  • Send data to the server - in the background

The Ajax web programming constitutes the assemblage of testified technologies like CSS, XHTML, XML HTTP request (XHR) and JavaScript. Ajax web development technologies are adaptable to all JavaScript-enabled browsers irrespective of their operating system. Moreover, Ajax programming techniques recognize an impressive range of Eclipse-based web development tools that are open source and may be downloaded and used free of cost. Well-applied Ajax programming is an advantage for every web application, simple web sites or complex business applications.
