2. Five Parts of a State: A state has five parts:
State Name – Name of State
Entry – Action performed on entry to state
Do Activity – Action performed on entry to state
Exit State – Action performed on leaving state
Deferrable Trigger – A list of events that are not handled in that state but, rather, are postponed and queued for handling by the object in another state

4. Composite State Example
A state which has substates (nested states) is called a composite state.

5. Orthogonal State
A composite state with two or more regions is called orthogonal.
Unlike composite states, submachine states are intended to group states, so you can reuse them. Orthogonal state is divided into two or more regions separated by a dashed lin

6. Orthogonal State Exmaple
State Machine Diagram example: Computer Testing
This example represents two sets of concurrent substates by using two regions.
