2.4 Input-Processing-Output (I-P-O) Model

Definition: Computer Systems Work on the Input-Process-Output Model

Components:

  • Input
  • Process
  • Output

Key Aspects:

  • Input: Data given to the system
  • Process: Operations performed by the system
  • Output: Results presented by the system

Input:

Requirements from the environment

Processing:

Computation dependent on the input requirements

Output:

Results presented to the environment

Purpose:

Allows breaking down problems into three core components for analysis
