Imagine you and your friend are sending messages using flashlights in a dark room. Each flashlight represents a signal that can be on or off. Microchips use similar flashes of light, but much faster, to send information to each other, like how a phone talks to a computer. The on-and-off signals help them understand what the other is saying.
Examples
- A flashlight message between two friends
- A phone sending a text using tiny on/off switches
