1. How Does a Keyboard Work?

Keyboards are like super-fast messengers between you and the computer:

1. Press a Key: A tiny circuit closes under the key.
2. Signal Sent: The keyboard tells the CPU which key you pressed.
3. Screen Shows: The letter/number appears!

⚡ Fun Fact:

The CPU checks the keyboard 100+ times per second to see if you typed anything!

Activity:

Unplug your keyboard while typing—what happens? (Spoiler: Letters freeze!)
