Which of the following best describes Alphabet?
Difficulty: Easy
About this MCQ
This Easy Theory of Computation (Automata) question asks: Which of the following best describes Alphabet? The correct choice is B. A finite, non-empty set of symbols used to construct strings in a formal language.. 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 property of a problem indicating whether an algorithm can be constructed that always provides a correct yes/no answer.
Why not A: “A property of a problem indicating whether an algorithm can be constructed that always provides a correct yes/no answer.” does not fit this question. The answer is A finite, non-empty set of symbols used to construct strings in a formal language..
- B. A finite, non-empty set of symbols used to construct strings in a formal language. ✓
- C. The undecidable problem of determining whether a given program will finish running or continue forever.
Why not C: “The undecidable problem of determining whether a given program will finish running or continue forever.” does not fit this question. The answer is A finite, non-empty set of symbols used to construct strings in a formal language..
- D. An abstract computational model that manipulates symbols on an infinite tape according to a set of rules.
Why not D: “An abstract computational model that manipulates symbols on an infinite tape according to a set of rules.” does not fit this question. The answer is A finite, non-empty set of symbols used to construct strings in a formal language..
Correct answer
B. A finite, non-empty set of symbols used to construct strings in a formal language.
Explanation
