# Is a state machine a Turing machine?

## Is a state machine a Turing machine?

A Turing machine is a finite state machine plus a tape memory. Each transition may be accompanied by an operation on the tape (move, read, write). Its total possible configurations are arbitrarily large, regardless of the size of the program; it expands towards infinity.

What is more powerful a Turing machine or a FSA?

Note that Turing machines are more powerful than FSA, PDA, and LBA (linear-bounded automata) – recall the Chomsky hierarchy. By power, we mean the ability to recognize more languages.

### What is state machine programming?

A state machine is a programming architecture that allows dynamic flow to states depending on values from previous states or user inputs. This architecture is suitable for applications that can be described as a combination of: States. Decision-making logic that determines when to move to a particular state.

How Turing machine is different from other automata?

Therefore, the major difference between a Turing machine and two-way finite automata (FSM) lies in the fact that the Turing machine is capable of changing symbols on its tape and simulating computer execution and storage.

## Why Turing machine is most powerful?

If you look at computational complexity, a Turing Machine is the most powerful machine – because it has unlimited memory, and no real machine has that. Any real machine cannot solve problems of arbitrary size; they cannot even read a problem, much less solve it.

What language does the Turing machine use?

Recursive Enumerable Languages

Turing Machine was invented by Alan Turing in 1936 and it is used to accept Recursive Enumerable Languages (generated by Type-0 Grammar).

### Why is Turing machine more powerful than FSM?

AnswerÂ» c. turing machine has capability remember arbitrary long sequence of input string.

Does a Turing machine have infinite memory?

Turing machines are similar to finite automata/finite state machines but have the advantage of unlimited memory. They are capable of simulating common computers; a problem that a common computer can solve (given enough memory) will also be solvable using a Turing machine, and vice versa.

## Why do we use Turing machine?

Turing Machine was invented by Alan Turing in 1936 and it is used to accept Recursive Enumerable Languages (generated by Type-0 Grammar). A turing machine consists of a tape of infinite length on which read and writes operation can be performed.

Can a Turing machine accept any language?

The turing machine accepts all the language even though they are recursively enumerable.

### Can Turing machines recognize any language?

Turing machines (TM)
Finite state automata can be used to recognize only regular languages. To recognize a context-free grammar, we need to use a pushdown automaton.

Can a Turing machine loop forever?

turing(turingDescrip) can neither halt nor loop forever; it doesn’t make sense either way.

## Which language is accepted by Turing machine?

recursively ennumerable
Explanation: The language accepted by Turing machines are called recursively ennumerable (RE), and the subset of RE languages that are accepted by a turing machine that always halts are called recursive. Explanation: We can refer to languages as ‘recursive’ and problems as ‘decidable’.

What language does a Turing machine recognize?

Recognizable Language A Turing machine M recognizes language L if L = L(M). We say L is Turing-recognizable (or simply recognizable) if there is a TM M such that L = L(M). Decidable Language A Turing machine M decides language L if L = L(M) and M halts on all inputs.

### Can Turing machine have infinite loop?

No Turing machine can infallibly tell in advance if another Turing machine will get stuck in an infinite loop on some given input.

What type of language is accepted by Turing machine?

## What languages can Turing machines recognize?

Do Turing machines have infinite memory?

### Can a Turing machine recognize all languages?

Can a Turing machine accept an infinite language?

Yes, a Turing machine can decide that langauge: it just looks at the first character and accepts or rejects without even needing to look at the rest of the string.

## Can a Turing machine accept any regular language?

How many types of Turing machines are there?

Multi-dimensional Tape Turing Machine:
It has multi-dimensional tape where the head can move in any direction that is left, right, up or down. Multi dimensional tape Turing machine can be simulated by one-dimensional Turing machine.

### What is halting problem of Turing machine?

The halting problem is a decision problem about properties of computer programs on a fixed Turing-complete model of computation, i.e., all programs that can be written in some given programming language that is general enough to be equivalent to a Turing machine.

Can Turing machine recognize all languages?

## What languages are not Turing complete?

Data Languages like HTML, XML, JSON and Markdown are always Non Turing Complete Programming Languages as they are designed to represent data and not computation.
