Hi Prasad,

When we write Events and methods inside the component controller those becomes visible throughout the components. So, for example, any action of a view of the component can call such a method of the component controller.

And when we write an Event or Method inside an individual component, it's life cycle remains inside the component only.

This is the basic difference.

Moreover, If you create attributes insdie component controller those becomes known to all methods that are called within a component and can be used by them, provided they have the Public property.

Hope it helps...
