Action node	Activity node
The executable, atomic computations such as sending a signal to an object, creating or destroying object are called as action node.	An ongoing non-atomic computation within an activity diagram is called as Activity node.
Action node cannot be decomposed.	Activity node can be further decomposed in multiple activities.
It gives immediate result. Takes less time for execution.	It may take some time duration to complete the execution.
Example:- Action node in the above example performs action as increment of value Index.	Example:- Activity node in the above example can be further divided into multiple activities or actions
