Difficulty: Medium
About this MCQ
This Medium Theory of Computation (Automata) question asks: In computer science, Formal language refers to which of the following? The correct choice is C. A set of strings composed of symbols from a defined alphabet.. 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. The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages.
Why not A: “The concept where a DFA and an NFA are considered equivalent because they recognize exactly the same class of languages.” does not fit this question. The answer is A set of strings composed of symbols from a defined alphabet..
- B. A grammar for which some string can be generated by more than one distinct derivation tree.
Why not B: “A grammar for which some string can be generated by more than one distinct derivation tree.” does not fit this question. The answer is A set of strings composed of symbols from a defined alphabet..
- C. A set of strings composed of symbols from a defined alphabet. ✓
- D. The process of reducing a deterministic finite automaton to the smallest possible number of states while preserving its language.
Why not D: “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 set of strings composed of symbols from a defined alphabet..
Correct answer
C. A set of strings composed of symbols from a defined alphabet.
