# Automata Or Computation Assignment Help

Automata are the study of Abstract Computing Devices in computer science. In simple words you can say Automata is a mechanism in which a system is set to motion once and can operate continuously and independently. Automata word is basically taken from a Greek word named “Automaton”. It is a purely concept of theoretical computer science in which a mechanism can move or work itself. Automata are basically based on two principles that are physical and logical under which any electromechanical device can perform and can convert an input from one form to another. This input can be any information that can be converted into one form to another or into any action on the basis of given or applied algorithm. An automaton is a mathematical procedure which is used to compute the problems in a simpler way. An automata theory is used which can be related to a theory of formal language. An Automata is used to represent this formal language which can have a finite set of input (Input can be a set of symbols or letters, which is known as an alphabet). The theory which is concerned with models which are used to process objects and simulation like ATM (Automated Teller Machine), Computers, digital circuits, robotics, etc is known as Theory of Automata and the theory which is used to compute a problem efficiently using an algorithm is known as Theory of Computation. The composition of Computer Science Assignment can now be easy if you intend to avail Automata or Computation Assignment Help from the experts to know more about it.

Automata can be stated as “automatic”. An automaton is an abstract machine called a mathematical object which has two main states that are initial (start) and final (target) state. When there is an input symbol then there is a change from one state to another known as transition between the two states. In an automaton there are states (represented by circles) and transition (represented by arrows).

## How does it work?

An automaton works on a sequence of input which is given on discrete time steps. An input can be a sequence of symbols known as word. An automaton reads input in a sequence they are and as in an automaton there are n number of states so at every input its is in any one state. According to the input symbol it transits from one state to another until the whole word is not read and it is decided on the final state that whether to accept the word or to reject it. In this way, an automaton works and the final accepted sequence of symbols is published as language accepted by the automaton. An example of an automaton is a Turing Machine that is used to compute the computational power of a computer.

### THERE ARE TWO MAIN TYPES OF AUTOMATA

Deterministic-Finite Automata: when there is an input symbol then after reading it, the automaton can jump only to one and only one another state.

Non-Deterministic Finite Automata: when there is an input symbol then after reading it, the automaton can jump to number of states.

### THREE MAIN CLASSES OF AUTOMATA ARE·

• Discrete
• Continuous
• Hybrid

Some of the applications of automata are as in text processing, compilers, etc finite automata is used. In robotics automata is used widely as robots work itself when once they are set to start working. Theory of automata can be seen in many machines working around us in daily routine. However, after all the information mentioned here, it is still advisable to get Automata or Computation Assignment Help from the experts to get pertinent information.
