AJAX is based on the following open standards:
The open standards used in AJAX are well defined, and supported by all major browsers. AJAX applications are browser and platform independent. (Cross-Platform, Cross-Browser technology)
There is nothing new to learn.
AJAX is based on open standards. These standards have been used by most developers for several years.
Most existing web applications can be rewritten to use AJAX technology instead of traditional HTML forms.
A traditional web application will submit input (using an HTML form) to a web server. After the web server has processed the data, it will return a completely new web page to the user.
Because the server returns a new web page each time the user submits input, traditional web applications often run slowly and tend to be less user friendly.
XML is commonly used as the format for receiving server data, although any format, including plain text, can be used.
