Summary

This is a short introductory unit of four lessons covering sections 1.1 – 1.3 of the OCR J276 specification. It is ideal for teaching at the beginning of the course or as a discrete unit later in the order of study. The unit begins by looking at the various components of the CPU used in the Von Neumann architecture. Subsequent lessons build on the fundamentals covered at KS3 in our unit of Understanding Computers unit, concentrating on RAM, ROM, cache and the need for virtual memory. The unit concludes by examining the need for secondary storage devices and their practical advantages in given applications.

What people say...

From what I have seen so far of your units, which is most of them, I really like the approach, hence me buying more and more of them. It has saved me a huge amount of time and will give us a standardised approach for yrs 7-9.

I have found the units I have already purchased really helpful and love the fact they are all editable Office documents.
