Most of the people will surpised to hear someothing about AJAX.AJAX is not a new programming language.It is a new feature that we use in our website. AJAX stands for Asynchronous Javascript and XML. Let us look the whole view in detail abot AJAX.AJAX was first used by google.And after that people started using AJAX in there own website.The advantage of AJAX is whenever we send information from browser to server.The whole data is send and server returns the whole HTML page to the client.By using AJAX not the whole data is send.Instead of that part of the information is send which is necessary and server return doesnot return the whole page.It sends the required information which we want.So the updation is not done to whole page but part of the page is updated.SO the response is fast compare to other pages where there is no AJAX.
