Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Theoretical computer science?Computability, complexity theory (P vs. NP), algorithm analysis, cryptography, automata theory
2. What is the primary methodologies?Mathematical proof, logical deduction, and abstract modeling
3. What is the foundational models?Turing machines, finite automata, and formal grammars
4. Why do we need theoretical computer science?It helps us know which problems can be solved by a computer, how fast they can be solved, and what limits exist. This knowledge lets us make better programs and secure online communications.
5. How did Alan Turing help computers?Alan Turing invented a simple machine that could simulate any computer program. His idea of a universal computing machine showed that a single machine could do all kinds of calculations, which is the basis for modern computers.

Computational Complexity: The study of the resources (time, space) required to solve computational problems.
P vs. NP Problem: A major unsolved problem asking if every problem whose solution can be quickly verified can also be quickly solved.
Automata Theory: The study of abstract machines and the computational problems they can solve.
Cryptography: The science of secure communication, often relying on computationally hard mathematical problems.
