What does the arrow between states in a state transition diagram signify?

In a state transition diagram, the arrow between states signifies a transition between states. This means that the arrow represents the movement from one state to another as a result of an event or condition. Each arrow indicates how the system is expected to change from the current state to the next state when specific events occur. This transition is essential for understanding the dynamic behavior of the system being modeled.

The focus of state transition diagrams is to track how different events can lead to changes in the state of a system, and the arrows are a visual representation of these potential changes. Each state signifies a distinct condition of the system, while the arrows illustrate the possible transitions that can occur due to various actions or events, making it clear how the system can evolve over time.
