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...

Absolutely perfect in terms of content, accessible to all and yet contain some challenging activities. I can focus on explaining the concepts, demonstrating where needed and most importantly, providing help and support to the students. A* or a grade 9 from me!

Alex Gannon. Computer Science Teacher, Thomas Hardye School

Love your books!  We have given our GCSE cohort copies of J277 textbook AND the ClearRevise books. Hopefully we will do the same with Python Challenge books.
