Traditional computer systems
Lesson details
Learning outcome
I can describe how general-purpose computers use programs to process different types of data and perform a wide range of tasks.
Key learning points
- Computers follow instructions called programs to perform tasks.
- Programs tell the computer how to process data, such as numbers, text, or images.
- A general-purpose computer can run many different programs, unlike a single-purpose device, which is built for one job.
Keywords
Computer - an electronic device that processes data and performs tasks
Program - a set of commands that can be run by a computer in order for it to do a task
Common misconception
All computers can do everything equally well.
General-purpose computers can run many programs, but single-purpose computers are designed to do one task very efficiently.
Teacher tip
Try to make the lesson interactive by having students list devices they know and decide if they are single-purpose or general-purpose. Or, show pictures and ask students to guess which type of device it is and why.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
