Hi Praba,

In general "asynchronous" would mean "event-driven" as in comparison to "polling".

A simple example I can think of would be the way that in all modern GUI frameworks (for example Microsoft's MFC) you do not have to poll the keyboard or mouse port for input but rather write code in event handlers that responds to events that are automatically generated by the GUI framework.

In the same way - in Twisted you are coding event-handlers rather than writing polling routines that would for example poll a network socket for data.
