AQA Computer Science GCSE

This page is up to date for the new AQA 8525 syllabus for the 2022 exam. Make sure you check the revision pages to see which topics will be on the 2022 exam.

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 nine parts, although the order I teach these in will vary depending on how I'm doing for time. Some of the parts are short and others quite complex and detailed.

  1. Software types & OS
  2. Systems architecture
  3. CPU Performance
  4. Fetch-Execute Cycle
  5. Memory
  6. Secondary Storage
  7. Embedded systems
  8. Languages & translators
  9. Boolean logic

Boolean logic crosses over with practical programming skills from unit 2 whilst cloud storage, part of the secondary storage section, has its own section in unit 8.
