Hi Shivansh,
Advantages-The whole Web page would be compact.One wont have to scroll through large paragraphs.Waiting Time is reduced.Bandwidth Usage- Since pages do not have to completely reload, it can help in less server bandwidth (helpful for me in my college), and when you are in countries or places that charge for your hosting bandwith, it will be more efficient,
Traffic to and from the server is reduced.
Form Validation.
User Simplicity.
Speed.
Disadvantages-If you press the back button, you may not be able to return in the previous state.Might be difficult to bookmark and return to that particular state of the application
2. The second idea was to put JQuery into use.
I have a few more queries though.1. Could someone tell me about Hackathon & what role can I play, depending on my proposal?2. How do I present my talk (if I am allowed)..like present a modified page with AJAX usage as well?3. Could I have a contact no. of someone incharge so that I can speak directly, in case for some minor queries.
