List and describe the elements that each hardware input, output, or storage device within a computer requires.

Hardware input,output,or storage devices require software to function. Software refers to the set of instructions that directs the hardware to accomplish a task. Software uses hardware for four basic functions:input, processing,storage and output. Also hardware components must communicate both data and instructions among themselves, which requires an electrical system to provide power. Every communication between hardware and software, or between software  and other software is reduced to a simple yes or no, which is represented inside the computer by two simple states: on and off.
