Difficulty: Hard
About this MCQ
This Hard Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Which of the following best describes Deterministic finite automaton (DFA)?”
The accepted answer is B. A finite automaton where each state has exactly one transition for each possible input symbol.. Deterministic finite automaton (DFA) refers to a finite automaton where each state has exactly one transition for each possible input symbol.
- A. An automaton that uses a stack to recognize context-free languages.
Why not A: “An automaton that uses a stack to recognize context-free languages.” is not correct. The accepted answer is B. A finite automaton where each state has exactly one transition for each possible input symbol.. Deterministic finite automaton (DFA) refers to a finite automaton where each state has exactly one transition for each possible input symbol.
- B. A finite automaton where each state has exactly one transition for each possible input symbol. ✓
- C. A formal grammar in which every production rule has a single non-terminal on its left-hand side.
Why not C: “A formal grammar in which every production rule has a single non-terminal on its left-hand side.” is not correct. The accepted answer is B. A finite automaton where each state has exactly one transition for each possible input symbol.. Deterministic finite automaton (DFA) refers to a finite automaton where each state has exactly one transition for each possible input symbol.
- D. A visual representation showing how an automaton moves between states based on input symbols.
