What is AJAX?

1. AJAX is an acronym for Asynchronous JavaScript and XML.
2. AJAX is a new technique for creating better, faster, and more interactive web applications.
3. With AJAX, a JavaScript script can communicate directly with the server, with the XMLHttpRequest object. With this object, a JavaScript can exchange data with a web server, without reloading the page.
4. 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 entire pages.
5. The AJAX technique makes Internet applications smaller, faster and more user-friendly.
