With AJAX, you can change parts of a web page without having to load the whole page again.
The letters AJAX stand for \”Asynchronous JavaScript and XML.\” It\’s a collection of technologies that work together, such as JavaScript, DOM, XML, HTML/XHTML, CSS, XMLHttpRequest, etc.
AJAX lets you send and get data at different times without having to reload the web page. So it\’s quick.
AJAX lets you send only the important parts of a page to the server, instead of the whole page. So, only useful information from the client is sent to the server. It makes your app faster and more interactive.

Describe AJAX.
AJAX = JavaScript and XML that run in parallel.
AJAX is a way to make web pages that load quickly and change all the time.
AJAX lets small amounts of data be sent back and forth between the server and the web page in the background. This lets web pages be updated at different times. This means that parts of a web page can be changed without having to reload the whole page.
Traditional web pages that don\’t use AJAX have to reload the whole page when the content changes.
Google Maps, Gmail, YouTube, and the tabs on Facebook are all examples of applications that use AJAX.
AJAX is Based on Internet Standards
AJAX is based on the standards of the internet and uses a mix of:
XMLHttpRequest object (to exchange data asynchronously with a server)

Why and when AJAX became popular
With Google Suggest in 2005, Google helped spread the word about AJAX.
AJAX is being used by Google Suggest to make a very dynamic web interface: When you start typing in Google\’s search box, the letters are sent to a server by a JavaScript. The server then sends back a list of suggestions.
