<human>:  When you say that a computer is a “black box”, what do you mean?
<bot>: A black box is a device that you can’t see into. You can’t see the internal workings of a computer. Computers are essentially black boxes, but they are not completely opaque. Computers have inputs, and outputs, and algorithms that process the inputs and produce the outputs. Computers are capable of doing many things, but we can’t always explain how they do them.
