Which of the following best describes the tape of a standard Turing Machine?

Options

  • A. A fixed-size memory register
  • B. An infinite sequence of cells used for reading and writing
  • C. A temporary input buffer only
  • D. More than one of the above
  • E. None of the above

Correct Answer (Detailed Explanation is Below)

B. An infinite sequence of cells used for reading and writing

Detailed Explanation

  • Tape: An unbounded sequence of cells used to store symbols.
  • Operations: The machine can read and write symbols on the tape.
  • Blank Cells: Initially, cells outside the input contain blank symbols.
  • Exam Point: The tape acts as the memory of a Turing Machine.
