1.Start/Initial Nodes		It shows the starting point of the activity diagram. An initial or start node is depicted by a filled circle with black color.
2.Final/Exit Node		It shows the exit point of the activity diagram. An activity diagram can have zero or more activity final nodes. Final node is rendered as two concentric circles with filled inner circle.
3.Activity		Activity is parameterized behavior represented as coordinated flow of actions. An activity is the process being modeled, such as washing a car. An activity is a set if actions.
4.Transition/Edge/Path		The flow of the activity is shown using arrowed lines called edges or paths. The arrowhead on an activity edge shows the direction of flow from one action to the next. A line going into a node is called an incoming edge, and a line exiting a node is called an outgoing edge.
