What the quiz covers
Theory of computation carries steady marks in GATE CSE every year, and this quiz covers the classic question types. The 25 questions are grouped into 8 areas, shown above each question: Automata, Regular languages, Context-free, Grammars, Chomsky hierarchy, Decidability, Regular expressions, Complexity.
A sample question explained
"Context-free languages are NOT closed under" The answer is Intersection and complement. The intersection with a regular language is still context-free. A quick counterexample for intersection: {aⁿbⁿcᵐ} ∩ {aᵐbⁿcⁿ} = {aⁿbⁿcⁿ}, which isn't context-free.
More questions you'll meet
A few of the other Theory of computation questions in the bank:
- Which language is not regular?
- Which machine recognises context-free languages?
- { aⁿbⁿcⁿ | n ≥ 0 } is
- Which grammar type generates recursively enumerable languages?
- The halting problem is
- Rice's theorem says that
- How many states does the minimal DFA for 'strings ending in ab' over {a, b} have?
Study tips
- Draw the DFA for each automata question before looking at the options.
- Make a closure-properties table for regular, context-free and recursive languages.
- Aim for at least 20 out of 25 on two separate attempts before you treat Theory of computation as revised; one lucky score can hide gaps.
Questions and options are shuffled on each attempt, so a retake is a fresh test. The Theory of computation questions were written by Uncodemy for practice; they aren't copied from any exam or company test.
Frequently asked questions
Is this GATE level?
Yes, at the level of typical GATE one-mark questions.
Are proofs included?
No. The quiz tests results and recognition, not writing proofs.
Is the Theory of computation MCQ quiz free?
Yes. Every question in the Theory of computation MCQ quiz can be answered without signing up. When you finish your first round, we ask once for your name and WhatsApp number to show your score; after that the Theory of computation MCQ quiz and every other Uncodemy tool open straight away.
