What is an IPOS cycle in cellphone?

Computing systems require ways of getting data inputs to the system, so that they can process or act on the inputs, and can output results to various devices. To save time in the input stage, storage allows computers to save and access data in computer formats for quicker retrieval later. In a personal computer, the parts of this IPOS cycle correspond to specific hardware devices:

• input: keyboard, mouse, microphone, scanner, touchpad
• processing: happen mostly in the CPU, or central processing unit
• output: monitor, printer, speakers
• storage: hard drives, optical drives, solid state memory, cloud storage
