Summary

This unit fully resources the teaching of four topics that are ideal as an introduction to the Computer Science 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 Understanding Computers unit, concentrating on RAM, ROM, cache, registers 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...

“
”

PG Online resources offer a great deal of support for teachers, especially for those struggling to make the transition from ICT to Computer Science. I am also particularly impressed with the clarity of the explanations and the way that the topics are broken into manageable pieces that students will be able to understand.

Mr Neil Hattan. Head of Computer Science, St Mary's Menston
