Final answer:
State-Chart Diagrams comprise of states, transitions, events, and actions. They are used to model the behavior of a system or process.
Step-by-step explanation:
State-Chart Diagrams comprise of:
States: Simple or Composite
Transitions: between states
Events: causing transitions
Actions: due to the events
State-Chart diagrams are visual representations used in software engineering to model the behavior of a system or process. They can be used to depict the different states that an object can be in and the events that trigger transitions between those states.
