Ajax/web 2.0

Ajax is not a technology, but a group of technologies combined to manage efficient communications between your browser and the web server. It is a fascinating technique that provides an easy way to get information without needing to open and close multiple windows at the same time. With Ajax, web applications retrieve information directly from the web server without re-loading your web page. The web page content is updated in the background. It ensures that only relevant data is refreshed.
