Theory of Computation (Automata)
Identify the correct definition of Universal Turing machine.
Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) question asks: Identify the correct definition of Universal Turing machine. The correct choice is B. A Turing machine capable of simulating any other Turing machine given its description and input.. Read the options below, commit to one, then use the explanation to see why that choice holds and why the others do not.
Theory of Computation (Automata) items like this one are written for Pakistan exams such as CSS, FPSC, PPSC, and NTS. The difficulty label is a hint about how much of the topic the stem assumes, not a score. Tags and exam names, when they are present, tell you where else the same idea is tested. Previous and next links stay in Theory of Computation (Automata) so you can continue the subject. Related questions point at nearby stems if you want another angle on the same idea.
Treat the explanation as part of the question, not a footnote. If you missed it, reread the stem against the correct option before you open the next Theory of Computation (Automata) item. A timed quiz is the same pool with a clock and a score. A past paper is a full sitting rather than this single question.
- A. A class of languages for which a Turing machine will accept and halt on strings in the language, but may not halt on strings outside it.
Why not A: “A class of languages for which a Turing machine will accept and halt on strings in the language, but may not halt on strings outside it.” does not fit this question. The answer is A Turing machine capable of simulating any other Turing machine given its description and input..
- B. A Turing machine capable of simulating any other Turing machine given its description and input. ✓
- C. The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.
Why not C: “The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.” does not fit this question. The answer is A Turing machine capable of simulating any other Turing machine given its description and input..
- D. A set of strings composed of symbols from a defined alphabet.
Why not D: “A set of strings composed of symbols from a defined alphabet.” does not fit this question. The answer is A Turing machine capable of simulating any other Turing machine given its description and input..
Correct answer
B. A Turing machine capable of simulating any other Turing machine given its description and input.
Explanation
A Turing machine capable of simulating any other Turing machine given its description and input option B is the accepted answer to Identify the correct definition of Universal Turing machine Option A A class of languages for which a Turing machine will accept and halt on strings in the language but may not halt on strings outside it does not fit this question Option C The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language does not fit this question Option D A set of strings composed of symbols from a defined alphabet does not fit this question For this Theory.
