How Do Computers Know What You're Typing?

Computers know what you're typing because each key on the keyboard sends a special message. When you press a key, it makes an electrical connection inside the keyboard that tells the computer which letter or symbol was pressed. The computer then shows that letter on the screen like magic! It’s like when you press a button on your phone, something happens instantly.
