Which device has no processing capability?

Answer 1

Hard to answer without a little more context, but which elements in a computer have no processing power? Pretty much anything but the CPU (Central Processing Unit) or processor, and the GPU (Graphics Processing Unit) also known as a video card.

If you meant devices that we use in our every day lives though, anything that calculates, displays, or returns information digitally has some sort of processing power. Something like a simple kitchen timer that uses a wound up spring that lets off pressure at a constant rate would be an example of a device with no processing capability.
