Computer Instructions

What are they?

So, what is a flowchart?

Flowcharts are a set of instructions which can be followed to complete a task.


A flowchart is an easy way to explain to someone on how to do something. For instance:-


If you wanted to make a cup of tea and didn't know how to someone could make you a flowchart on how to make a cup of tea with the use of a flowchart. See photo 1.


As well as being used for instructions, flowcharts can be used to solve basic problems by following a step to step guide which will help narrow down what is the possible problem and a way to fix it. See photo 2.

Computer Systems

What Is A Computer System?

A computer system is a mechanical/computer device that performs tasks that are set by default.



Where would I find a Computer System?

Everywhere. Computer systems can be found in your own home. They are normally very simple devices like toasters and fridges. Here are a few you might use everyday:




  • Toaster
  • Fridge
  • Alarm
  • Traffic Light



These may seem very unusual to you to be Computer Systems but they are. For instance your Alarm clock will have a set of instructions in it which tell it when and when not to set off and these instructions are set by you into a Computer System.

Computer System Flowcharts

When making a computer system you must have a set of instructions and an input and output much like a flowchart making it easy to follow.


What Would Happen If There Were No Computer Systems?

The world as we know it wouldn't exist. We rely on computer systems to perform important tasks every day. For instance cars wouldn't be able to corporate as no traffic lights and we would have no planes for they use computer systems. No alarm clocks, no cars and no computers! We need computer systems to live.
