Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) question asks: The concept in which an abstract computational model that manipulates symbols on an infinite tape according to a set of rules is best known as which of these terms? The correct choice is C. Turing machine. 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. Finite automaton
Why not A: “Finite automaton” does not fit this question. The answer is Turing machine.
- B. State transition diagram
Why not B: “State transition diagram” does not fit this question. The answer is Turing machine.
- C. Turing machine ✓
- D. Chomsky hierarchy
Why not D: “Chomsky hierarchy” does not fit this question. The answer is Turing machine.
Correct answer
C. Turing machine
Explanation
Turing machine (option C) is the accepted answer to “The concept in which an abstract computational model that manipulates symbols on an infinite tape according to a set of rules is best known as which of these terms”. Option A (Finite automaton) does not fit this question. Option B (State transition diagram) does not fit this question. Option D (Chomsky hierarchy) does not fit this question. For this Theory of Computation (Automata) question, the accepted answer is Turing machine.
