What is the difference between local hard disk and CPU?

Answer 1

The CPU (Central Processing Unit) processes information in binary form in computers by using logic gates which creates a certain response in an output, i.e. Speakers, Monitors, from an input, i.e. Keyboard, Mouse, Power Button.

The hard disk stores data such as documents, music and video. It is stored in binary form so it can be sent and processed by the CPU when you want to access it.

The better the CPU the more information can be processed at a time, i.e. higher quality video, higher quality photos.

The better the hard disk the faster the information can be passed to the processor. The bigger the hard disk the more information can be stored.
