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.

AQA Computer Science GCSE

July 2019: the AQA CompSci area is almost complete. Most of the content for units 3-6 is now up and there's quite a lot of Unit 7 material. There's still some work to do, particularly on Paper 1 units, but it's getting there.

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
  2. Hardware and Software/Software types
  3. Systems architecture
  4. Fetch-Execute cycle
  5. CPU Performance
  6. Memory and 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>
