This approach allows each input and output scenario to be studied and tested.Īn FSM may be something very abstract, like a model for a business represented by an illustration, or it may be something concrete, like a vending machine or computer. Within an FSM, all states in consideration exist in a finite list and the abstract machine can only take on one of those states at a time. A set of expected states the system can exhibit.Ī finite state machine may be implemented through software or hardware to simplify a complex problem.A set of probable output events that correspond to the potential input events.The makeup of a finite state machine consists of the following: When a user inputs hitting certain buttons, the system knows to implement the actions that correspond. Finite state machine (FSM) is a term used by programmers, mathematicians, engineers and other professionals to describe a mathematical model for any system that has a limited number of conditional states of being. A practical example of a finite state machine is a set of buttons on a video game controller that are connected to a specific set of actions within the game.
