How a Turing machine executes a program?

A Turing machine, like an algorithm, executes on an input string of bits. This way, A Turing machine can simulate the fact that a program is made of many lines and thus it depends on what line a program is executing, and it can also simulate the fact that a program can react differently with different data in memory.

Are all computers Turing machines?

No. Modern computers are most notably bounded by finite memory. There are many ways to construct abstract machines with various subsets of their functionality / programmability, which leads to frequently seen whitepapers about how X or Y is Turing complete.

What are the applications of Turing machine?

Turing machines founds applications in algorithmic information theory and complexity studies, software testing, high performance computing, machine learning, software engineering, computer networks and evolutionary computations.

How can Turing machine be compared to computer?

Turing machines are equivalent to modern electronic computers at a certain theoretical level, but differ in many details. In the analogy with a computer, the “tape” of the Turing machine is the computer memory, idealized to extend infinitely in each direction.

Are Turing machines real?

Turing’s machine is not a real machine. It’s a mathematical model, a concept, just like state machines, automata or combinational logic. It exists purely in the abstract. (Although “real” implementations of the Turing machine do exist, like in this foundational computer science paper.)

What is Turing Test How is it done?

The Turing Test is a method of inquiry in artificial intelligence (AI) for determining whether or not a computer is capable of thinking like a human being. After a preset length of time or number of questions, the questioner is then asked to decide which respondent was human and which was a computer.
