How does asychronous AJAX application works?

Question

I get the gist. You can keep using the application even when the request is getting processed by server. But I want to learn its timing diagram as well.

So here user event happened. Consider the first even. Then the ajax engine handled it. But how will ajax engine handle the second, third and fourth user event? It is missed. Or will it be handled in second phase(that ajax eng-server one).?Clarify please.

Hi Prabhat,The diagram describes the following things. But they seem to have missed covering how to process each AJAX requests. How 
 The
     browser sends an HTTP request to the server through AJAX engine.
 The
     Server processes the AJAX requests and returns the response to browser
     through the same AJAX engine.
 The
     browser receives the AJAX response and updates the UI.
