Finite state machines may be described in more detail using a state diagram. The state diagram is a graph, which means that it is composed of a set of nodes and a set of arcs. Each node has a set of incoming arcs and a set of outgoing arcs. Moore outputs are associated with nodes. Mealy outputs are associated with arcs.

Finite-state machine - Wikipedia

A finite-state machine (FSM) or finite-state automaton (FSA, plural: automata), finite automaton, or simply a state machine, is a mathematical model of computation.It is an abstract machine that can be in exactly one of a finite number of states at any given time. The FSM can change from one state to another in response to some inputs; the change from one state to another is called a transition.
