A state machine is a mathematical model of computation. It is an abstract machine that can be in one of a finite number of states. The machine is in only one state at a time; it can change from one state to another when initiated by a triggering event or condition, which is called a transition.

A state machine is used to model the behavior of a system. The states represent the different modes or stages that the system can be in, and the transitions represent the events or conditions that cause the system to change from one state to another. State machines are a powerful tool for modeling the behavior of systems, and they can be used to design and implement algorithms, protocols, and other software. What is state machine with example? A state machine is a machine that can be in one of a finite number of states. The machine can change from one state to another in response to some inputs. An example of a state machine is a vending machine. The vending machine has a finite number of states, including "idle", "accepting coins", "dispensing product", and "out of stock". The machine changes from one state to another in response to inputs from the user, such as inserting coins or selecting a product.

### What is state machine in programming?

A state machine is a mathematical model of computation used to design both computer programs and sequential logic circuits. It is an abstract machine that can be in one of a finite number of states. The machine is in only one state at a time; the state it is in at any given time is called the current state. It can change from one state to another when initiated by a triggering event or condition; this is called a transition.

A state machine can be represented by a state transition table, which shows all possible states the machine can be in, and the triggering event or condition (if any) that will cause a change to the next state.

### What are the types of state machine?

There are two types of state machine: Mealy and Moore.

Mealy machines have outputs that depend on the current state and the inputs.

Moore machines have outputs that depend only on the current state.

Who invented state machines? There is no one inventor of state machines. The concept of a state machine was first proposed in the early 1800s by Charles Babbage and George Boole, but it wasn't until the mid-1900s that state machines began to be widely used in engineering and computer science. One of the first practical applications of state machines was in the design of digital logic circuits. In the 1970s, state machines gained popularity as a tool for modeling and understanding complex systems. Today, state machines are used in a wide variety of fields, from computer science and engineering to biology and economics. Is state machine a software? A state machine is a software component that can be in one of a number of states, and which can transition to different states in response to events or actions.
