State transition diagram

A state transition diagram is a visual representation that shows how a system changes from one state to another based on specific conditions or inputs. Imagine a traffic light: it transitions between red, yellow, and green states depending on timers and sensors. Each state has rules that determine what happens next, like changing to yellow after green. This diagram helps to understand complex processes by clearly illustrating each possible state and the transitions, making it easier to analyze how systems behave, such as computer programs, mechanical systems, or even everyday scenarios.
