1. Introduction

There are five very common terms that are linked to each other. They describe particular stages in information handling.  They are:

  • input
  • processing
  • output
  • storage
  • feedback

You are often asked for a definition of these terms in the exam.  Make sure you can explain them. 

Over the next few pages we will look at each term in more detail.
