The first video explores the first computers that had stored programs in the same memory space as the data required for them. This is known as the von Neumann architecture and is still the foundation principle on which most computers are still built today. We take the lid off a central processing unit and explain the key components including the registers, the control unit and the cache.
The second video explains how three common characteristics of a CPU affect the performance of a computer: clock speed, number of cores and the cache size. These are the three characteristics students need to know for GCSE.
An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system. The third video explains the concept at a depth required for GCSE with some examples of embedded systems that students can use in their own work.
