2. State diagram - Wikipedia

   en.wikipedia.org/wiki/State_diagram

   A state diagram for a door that can only be opened and closed. A state diagram is used in computer science and related fields to describe the behavior of systems. State diagrams require that the system is composed of a finite number of states. Sometimes, this is indeed the case, while at other times this is a reasonable abstraction.

3. UML state machine - Wikipedia

   en.wikipedia.org/wiki/UML_state_machine

   The state diagram from Figure 2 is an example of an extended state machine, in which the complete condition of the system (called the extended state) is the combination of a qualitative aspect—the state variable—and the quantitative aspects—the extended state variables. The obvious advantage of extended state machines is flexibility.

4. Finite-state machine - Wikipedia

   en.wikipedia.org/wiki/Finite-state_machine

   State diagram for a turnstile A turnstile. An example of a simple mechanism that can be modeled by a state machine is a turnstile. [4] [5] A turnstile, used to control access to subways and amusement park rides, is a gate with three rotating arms at waist height, one across the entryway.

5. Deterministic finite automaton - Wikipedia

   en.wikipedia.org/wiki/Deterministic_finite_automaton

   The figure illustrates a deterministic finite automaton using a state diagram. In this example automaton, there are three states: S 0, S 1, and S 2 (denoted graphically by circles). The automaton takes a finite sequence of 0s and 1s as input. For each state, there is a transition arrow leading out to a next state for both 0 and 1.

6. State-transition table - Wikipedia

   en.wikipedia.org/wiki/State-transition_table

   It is possible to draw a state diagram from a state-transition table. A sequence of easy to follow steps is given below: Draw the circles to represent the states given. For each of the states, scan across the corresponding row and draw an arrow to the destination state(s).

7. Control logic - Wikipedia

   en.wikipedia.org/wiki/Control_logic

   Control logic can be modeled using a state diagram, [2] which is a form of hierarchical state machine. These state diagrams can also be combined with flow charts to provide a set of computational semantics for describing complex control logic. [3] This mix of state diagrams and flow charts is illustrated in the figure on the right, which shows ...
