The Super Calculator
Imagine a calculator that can not only do maths (5+3, 10×2) but can also make decisions ("Is 7 greater than 5?", "Are both conditions true?"). That's the Arithmetic Logic Unit. Every time your computer adds numbers in a spreadsheet, checks if a password is correct, or decides whether to run an IF statement - the ALU is doing the work. It's called the "calculator of the CPU" but it's so much more powerful than that!
