AJAX = Asynchronous JavaScript and XML AJAX is not a new programming language but a technique for creating better faster and more interactive web applications.With AJAX your JavaScript can communicate directly with the server using the JavaScript XMLHttpRequest object. With this object your JavaScript can trade data with a web server without reloading the page.AJAX 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 AJAX technique makes Internet applications smaller faster and more user-friendly. With AJAX Internet applications can be made richer and more user-friendly. In traditional JavaScript coding if you want to get any information from a database or a file on the server or send user information to a server you will have to make an HTML form and GET or POST data to the server. The user will have to click the Submit button to send/get the information wait for the server to respond then a new page will load with the results.Because the server returns a new page each time the user submits input traditional web applications can run slowly and tend to be less user-friendly.With AJAX your JavaScript communicates directly with the server through the JavaScript XMLHttpRequest objectWith an HTTP request a web page can make a request to and get a response from a web server - without reloading the page. The user will stay on the same page and he or she will not notice that scripts request pages or send data to a server in the background.

Ajax is standing for Asynchrone javascript and xml this framework is used to submit reuquests to the server asynchornously so that the browser will be not frozen during the request submission and reception in addition the server will send only requested data instead of building an entire asp page for this raison.
