draw a diagram of IPO cycle

Answer 1

IPO model

The input–process–output model
The input–process–output (IPO) model, or input-process-output pattern, is a widely used approach in systems analysis and software engineering for describing the structure of an information processing program or other process. Many introductory programming and systems analysis texts introduce this as the most basic structure for describing a process.[1][2][3][4]
Overview
A computer program or any other sort of process using the input-process-output model receives inputs from a user or other source, does some computations on the inputs, and returns the results of the computations.[1] In essence the system separates itself from the environment, thus defining both inputs and outputs, as one united mechanism.[5] The system would divide the work into two categories:
