What do you mean by output?

An output device is any device used to send data from a computer to another device or user. Most computer data output that is meant for humans is in the form of audio or video. Thus, most output devices used by humans are in these categories. Examples include monitors, projectors, speakers, headphones and printers.

Is CPU a storage device?

Computer data storage devices are also classified by their distance from the processor, or CPU. The closest storage is memory, or RAM. This is the only kind of data storage that directly accesses the CPU.

Is CPU internal or external?

A motherboard provides the electrical connections by which the other components of the system communicate. The mother board includes many components such as: central processing unit (CPU), random access memory (RAM), firmware, and internal and external buses.

Can a computer run without a CPU?

It’s not a good idea to boot without your CPU, but some motherboards (some Asus) will give you an error message saying “no cpu installed”. But, nothing good can come from booting without your cpu. The CPU is needed to run the computer, but not needed for power to flow.
