Note: this syllabus content is a slightly amended version of the one published freely on the web by AQA. I have made very minor adjustments to remove some content less suitable for students to use and it is presented here simply to allow the children I teach to download a usable copy of the syllabus content. It is copyright AQA and reproduced here simply to make access easier for students. No attempt to claim copyright is being made, although I could have copied the text into my own interpretation...

AQA Computer Science GCSE

May 2019: this area of the site is being built just now. I’m making progress but there are areas where there is no content yet. That will get added over the next 6 months or so.

Computer Systems

This area is all about the ways in which computers work. That includes what goes on inside the "black box" of the computer system and how things fit together.

I break the syllabus here down into seven parts, although these are a little different to how the syllabus actually reads.

  1. Boolean logic - there is some more to add to this
  2. Hardware and Software/Software types
  3. Systems architecture
  4. Fetch-Execute cycle
  5. CPU Performance
  6. Storage types
  7. Embedded systems

There are some parts of this unit which crossover with the last part of Unit 2 - the ways in which programming languages work. Other parts cross into Unit 7./p>
