This Computing teacher video introduces the different parts of a computer and explains how they work together to complete tasks. It explores the roles of input and output devices, introduces the difference between hardware and software and explains how computer systems receive information, follow instructions in a program and produce outputs. Using familiar examples, including traffic lights and washing machines, the video demonstrates that many everyday computer systems follow the same input–process–output model.

The video breaks down these key computing concepts into clear, accessible explanations, helping teachers build confidence in introducing technical vocabulary and using real-world examples to develop pupils’ understanding. Throughout, the emphasis is on supporting teachers to explain how computer systems use different components to receive inputs, process information and produce outputs.

This video is part of Kapow Primary’s Computing videos, which help pupils develop their understanding of computer systems and digital technology. It encourages children to recognise how computers are used in everyday life and the different ways they can help us.
