      Lesson details

      Learning outcome

      I can describe how systems are made up of different parts that work together.

      Key learning points

      1. Systems are built using a number of parts.
      2. Input, process and output are all parts of a digital system.
      3. Computer systems can communicate with other devices.

      Keywords

      • System - a group of parts or components that work together to complete a task or solve a problem

      • Input - something that goes into a system to make it work

      • Process - the steps or actions taken to complete the task

      • Output - the result of data processed by a computer

      Common misconception

      Systems have to be made up of one part.

      Systems are made up of many parts or components working together.

      Teacher tip

      Pupils may think that things just 'work' - in this unit, you are looking at the bigger systems that make processes happen. Systems can be seen all around us and you should explore examples in and around school that will be familiar examples for pupils to understand what they are.
