Multiple Choice Questions: The Central Processing Unit (CPU) for Kids

📚 Quick Study Guide

• ⚙️ The CPU stands for Central Processing Unit. It's like the brain of your computer!
• 🧮 The CPU does all the calculations and makes the computer work.
• ⚡️ The CPU has different parts like the control unit and the arithmetic logic unit (ALU).
• ⏱️ Clock speed, measured in Hertz (Hz), determines how fast the CPU can execute instructions. A higher clock speed generally means a faster CPU.
• 🌡️ CPUs can get hot, so they need a cooler like a fan or liquid cooling.
