Your relatives are returning from an overseas journey and you intend to pick them up from the airport. In order to obtain their flight information and time of arrival you enter the official airport website and start the search. In the searching field you enter the name of the city your relatives arrive from and press search.
Then what happens?
The current page disappears, and a new page is loaded, the search results are listed. This is how all web based applications have been working up until now - in order to see results of any query it was necessary to wait for a new page to download.
Not anymore! Thanks to Asynchronic JavaScript technology it will soon be possible to save that process, by that the exchange of information between the server and the web page will include only information that has changed, instead of downloading the whole page over again. This way, many other graphic elements that are static (such as the Logo) won't have to be repeatedly downloaded each and every time some other content of the page is changed.
Among the first to utilize AJAX Technology were Google with their "Google Suggest" You can try their new software Here. Pay attention to their built-in feature which provides auto-complete options for the keyword search while you enter it (without need for additional downloading).
AJAX Technology isn't some new concept, but a collection of existing tools and procedures and the coordination between them. A massive usage of this technology has been triggered by its first utilization by Google.
