How Does a Computer Know What You're Typing?

Imagine your keyboard is like a secret message sender. Every time you press a key, it sends a special code to the computer. The computer knows what letter that code means and shows it on the screen. It’s like having a tiny translator between your fingers and the screen. ## How Keys Work When you push a key down, it makes an electrical connection inside the keyboard. This tells the computer that something happened. Each key has its own number, so the computer knows which letter to show. The whole thing happens super fast, so fast, you don’t even notice!
