Explain why the operating system is important.
A: It allows all applications to run smoothly and manages the computer’s resources.
Why is AI considered a branch of computer science?
A: It studies how to make machines simulate intelligent behavior
Write a short explanation of how a function can help Karel complete repetitive tasks.
A function is a named set of commands that Karel can run multiple times to avoid rewriting code. Example: def turnRight(): turns Karel right by turning left three times.
