AJAX stands for "Asynchronous Javascript and XML".It is Not a stand-alone language or technology.It is a technique that combines a set of known technologies in order to create faster and more user friendly web pages. It is a client side technology.
Purpose of AJAX :
- Prevents unnecessary reloading of a page.
- When we submit a form, although most of the page remains the same, whole page is reloaded from the server.
- This causes very long waiting times and waste of bandwidth.
- AJAX aims at loading only the necessary innformation, and making only the necessary changes on the current page without reloading the whole page.
AJAX uses:
- Javascript (for altering the page)
- XML (for information exchange)
- ASP or JSP (server side)
