What is computer science?

The branch of computer science that studies the logical and mathematical properties of problems and algorithms, rather than focusing on specific computers or software.

What is an algorithm?

A step-by-step set of instructions for solving a problem or completing a task. It must be unambiguous, effectively computable, and have a finite number of steps.

What are iterative operations?

A type of algorithm operation that involves repeating a set of instructions a specified number of times or until a condition is met.

What was the ENIAC computer?

The first electronic general-purpose computer built in 1946. It was massive and used vacuum tubes for processing. It played a crucial role in World War II.
