1	State		A state is a condition or a situation in the life of an object during which it satisfies some conditions, performs some activity or waits for some events. It is represented with a rounded rectangle. Name of the state is written inside the rectangle.
2	Initial State		It indicates the default starting place of the state diagram. An initial state is represented as filled circle.
3	Final State		Final state indicates end of the execution of the system. It is represented as a filled black circle surrounded by an unfilled circle
