WHAT ARE THE STATE MACHINES.

INTRODUCTION:

A state machine is any device storing the status of something at a given time. The status of something at a given time. The status changes based on inputs, providing the resulting output for the implemented changes. A finite state machine has finite internal memory. Input symbols are read in a sequence producing an output feature in the form of a user interface.

                                                State machines are represented using state diagrams. The output of a state machine is a function of the input and current state. State machines play a significant role in areas such as electrical engineering.

                                                                           The operation of a state machine begins from a start state. On a successful transition it ends up in an accept state. The transition takes place based on the inputs provided. The current state depends on the past states of the systems. The number of states formed depends on the available states of memory. A transition is enabled  based on certain conditions and indicates a state change. An action describes an activity performed at the given moment. The different types of actions are transition actions, input action, entry and text action.
