This video talks about an introduction to AJAX. It is not a new programming language, but a new technique for creating better, faster and a more interactive web application which makes web user experience much better.

With AJAX, a JavaScript can communicate directly with the server, with the XMLHttpRequestobject. With this object, a 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. As most of the webmasters are adopting this technology for their websites.

One thing to note is that AJAX is based on the following web standards:

• JavaScript
• XML
• HTML
• CSS
