1. AJAX is an acronym for Asynchronous JavaScript and XML

2. Ajax gives the user, the ability to dynamically and asynchronously interact with a web server, without using a plug-in or without compromising on the user's ability to interact with the page

3. A JavaScript script can communicate directly with the server, with the XMLHttpRequest object

4. A JavaScript object can exchange data with a web server, without reloading the page

5. AJAX uses asynchronous data transfer between the browser and the web server, allowing web pages to request small bits of information from the server instead of entire pages
