Traditional computer systems

I can describe how general-purpose computers use programs to process different types of data and perform a wide range of tasks.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. Computers follow instructions called programs to perform tasks.
  2. Programs tell the computer how to process data, such as numbers, text, or images.
  3. 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 instructions that tells a computer what to do

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.


To help you plan your year 8 computing lesson on: Traditional computer systems, download all teaching resources for free and adapt to suit your pupils' needs...

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.
