The various implications of AJAX can be sumarized as follows....

Pros and Cons

Pros
1. Bandwidth Utilization: Since AJAX works on the principle of sending a relatively small amount of data from the client Machine on to the server,the bandwidth utlilization is comparitively small. Ajax pages seems to load quickly as the payload coming from the server is relatively small.

2. Multitasking: The idea of multitasking can easily be seen while utilizing the concept of AJAX in web programming. AJAX can be used for multitude of works such as deleting,editing , returning search result etc without the whole pages being reloaded. This increases the interactivity of webpages

Cons
1. Unresponsive nature: Ajax pages seems to loose responsiveness. They therefore cannot be used for time critical applications.

2. AJAX application still has limited domain as they still cannot be used to interact with the hardwares like printer,webcams etc.

3. No fixed pattern of programming exist between the developers of the world so it becomes harder to communicate and exchange concepts .

4. AJAX application is very much dependent on the availibility of Internet connection
