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.
What is it used for?
Too many web apps, like Gmail, Facebook, Twitter, Google Maps, YouTube, etc., use ajax technology.
