Question
Explain FSM model.
Answer
The Finite State Machine (FSM) model mathematically represents a software system as a strict set of states triggered by external events.
The Finite State Machine (FSM) is a highly rigorous mathematical behavioral model. It explicitly conceptualizes the software system as a machine that can exist in exactly one specific operational "State" at any given millisecond. The machine violently transitions from one state to another strictly based on specific external inputs or triggered events, completely preventing undefined behavior.
