Imagine your keyboard is like a musical instrument, and each key plays a note. When you press a key, it sends a signal to the computer, telling it which note (or letter) was played. The computer listens and knows exactly what letter you pressed, just like how a musician knows which note was played on the piano.
Examples
- Pressing the 'A' key is like telling your computer: 'I want an A on the screen.'
- Your keyboard sends a message to your computer every time you press a letter.
- The computer reads the message and prints the letter on the screen.
