About this MCQ
This Medium Theory of Computation (Automata) MCQ checks one syllabus fact.
The question is: “Select the correct name for: a language that can be expressed using a regular expression or recognized by a finite automaton.”
The accepted answer is B. Regular language. Select the correct name for a language that can be expressed using a regular expression or recognized by a finite automaton is answered by Regular language option B Option A Deterministic finite automaton DFA does not match the stem it is a near-miss used to catch incomplete recall of Regular language Option C Turing machine does not match the stem it is a near-miss used to catch incomplete recall of Regular language Remaining alternatives Context-free grammar fall outside the same rule and should be eliminated once Regular language is identified Theory of Computation Automata questions of this type reward precise definitions rather than approximate associations Theory of Computation Automata recall of this distinction is a regular item in FPSC PPSC.
