Are headphones, radios, dishwashers, and remote controls considered Computers? Do any of them store data or process any data?

Yes, these things can be considered a computer. And they can also store and process data.

Explanation:

Headphones, radios, dishwashers, and remote controls are all computers because they all have some sort of logic board inside the device to control what it does. Example, a dishwasher has internal components that it uses to keep track of how long the wash/rinse cycle have lasted and how long they are supposed to last.

I hope that helps!
