This Computing video supports teachers in introducing the concept of RAM (Random Access Memory) and its role in helping computers process information quickly. It uses the example of the Mars Rovers to illustrate how the amount of RAM available has increased over time, allowing for more complex data processing. The video explains how memory is measured, from bits and bytes to kilobytes, megabytes and gigabytes, helping pupils grasp the scale of digital information. Teachers are reminded that RAM enables real-time thinking in computers, while the CPU (Central Processing Unit) handles processing, though it’s measured differently. A table is used to show the growth in RAM across the generations of Mars Rovers to reinforce these ideas.

This video is part of Kapow Primary’s Computing scheme of work – videos. It builds teachers’ confidence in explaining fundamental hardware concepts like memory and processing speed. By using a real-world context, the video supports teachers in making abstract ideas more concrete and engaging for pupils. The video prepares teachers to lead discussions around data handling, system performance and why hardware specifications matter in everyday digital technology.
