Black box

A black box is a type of device that does something, but it's not always clear how it is doing it. It looks like a box that is usually black, and it often has wires coming out of it. Sometimes, a black box is used to take in information and turn it into something else without us knowing how it's doing it. For example, your TV remote is like a black box. You put in certain commands (like pushing buttons on the remote), and it turns them into something that your TV can understand. That's the magic of a black box!
