Hi Ramesh,

actionSupport component adds AJAX support to other components in visualforce. It allows components to be refreshed asynchronously by calling the controller’s method when any event occurs (like click on button). It allows us to do partial page refresh asynchronously without refreshing  full page.

Refer the below link for examples and try it in your developer org to get clear idea.
