Which of the following statements about a Universal Turing Machine is correct?

Options

  • A. It can simulate the behavior of any Turing Machine given its description and input
  • B. It can solve every undecidable problem
  • C. It does not require an input tape
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

A. It can simulate the behavior of any Turing Machine given its description and input

Detailed Explanation

  • Universal Turing Machine (UTM): A theoretical machine capable of simulating any other Turing Machine.
  • Input: An encoded description of another machine and its input.
  • Concept: Provides the theoretical foundation for general-purpose programmable computers.
  • Important: A UTM cannot solve undecidable problems such as the general Halting Problem.
