What is the Chomsky hierarchy?

  1. A classification of formal languages based on their generative power.

  2. A classification of programming languages based on their features.

  3. A classification of natural languages based on their structure.

  4. A classification of computational models based on their complexity.

Show answer
Correct Option: A
Explanation:

The Chomsky hierarchy is a classification of formal languages based on their generative power, which is the set of strings that can be generated by the language.

Which of the following is a type of formal language in the Chomsky hierarchy?

  1. Regular languages

  2. Context-free languages

  3. Context-sensitive languages

  4. Unrestricted languages

Show answer
Correct Option:
Explanation:

Regular languages, context-free languages, context-sensitive languages, and unrestricted languages are all types of formal languages in the Chomsky hierarchy.

What is the difference between a regular language and a context-free language?

  1. Regular languages can be generated by a finite state automaton, while context-free languages can be generated by a pushdown automaton.

  2. Regular languages can be generated by a context-free grammar, while context-free languages can be generated by a regular grammar.

  3. Regular languages are closed under union, concatenation, and Kleene star, while context-free languages are not.

  4. Regular languages are more expressive than context-free languages.

Show answer
Correct Option: A
Explanation:

Regular languages can be generated by a finite state automaton, while context-free languages can be generated by a pushdown automaton.

What is the difference between a context-free language and a context-sensitive language?

  1. Context-free languages can be generated by a context-free grammar, while context-sensitive languages can be generated by a context-sensitive grammar.

  2. Context-free languages are closed under union, concatenation, and Kleene star, while context-sensitive languages are not.

  3. Context-free languages are more expressive than context-sensitive languages.

  4. Context-sensitive languages can be generated by a pushdown automaton, while context-free languages cannot.

Show answer
Correct Option: A
Explanation:

Context-free languages can be generated by a context-free grammar, while context-sensitive languages can be generated by a context-sensitive grammar.

What is the difference between a context-sensitive language and an unrestricted language?

  1. Context-sensitive languages can be generated by a linear bounded automaton, while unrestricted languages can be generated by a Turing machine.

  2. Context-sensitive languages are closed under union, concatenation, and Kleene star, while unrestricted languages are not.

  3. Context-sensitive languages are more expressive than unrestricted languages.

  4. Unrestricted languages can be generated by a context-sensitive grammar, while context-sensitive languages cannot.

Show answer
Correct Option: A
Explanation:

Context-sensitive languages can be generated by a linear bounded automaton, while unrestricted languages can be generated by a Turing machine.
