1. Introduction
An automated system is any system where an input
is provided and a machine or computer carries out a process that produces
an output.
For example, you may have used a vending machine.
You will have put money in and entered a code for the item you wish to
buy. These are the inputs. The computer carries out a process of taking
the code, working out what the user wants to buy, checking you have put
in enough money and then making the parts move that make the item release.
Your output is the item you have bought and your change.
You will have many automated systems at home:
- washing machines
- DVD players/recorders
- mobile phones
- microwave oven
Elsewhere, automated systems are used to:
- build cars in factories
- control traffic lights
- guiding aircraft
