About

A Computer Organization is a functional view of a computer in the computer architecture where:

  • Hardware components are presented as boxes
  • with input and output that connects to each other

It describes how a particular processor will implement the ISA

Computer organizations may vary depend on a manufacturer’s design, but they are all originated from the Von Neumann model

Example
