About Computer Systems
GoConqr OriginalWhat this unit covers
The resources here look at how a computer is put together and how its parts work. The mind map Unit 1.1 Systems Architecture breaks the CPU into its parts: MAR, MDR, CIR, ALU, CU, PC and the accumulator. Primary Storage compares RAM, ROM and cache, and notes that non-volatile memory keeps its contents when the power is off. Other maps cover input, output and storage devices, operating systems and utility software.
Where to start
Begin with the big picture. OCR Computer Science: Computer Systems separates hardware from software, with examples of each. Then open OCR GCSE Computer Science 1.1 for the CPU and its fetch, decode and execute cycle. The BIOS flowchart is a short way to see what happens when a computer is switched on, since RAM is empty and ROM holds the start-up instructions.
Using maps and quizzes together
Read a map first, then test yourself. After the CPU maps, try the CPU and Memory quiz. After the storage maps, try Secondary storage devices or the Input and Output device quiz. Any question you miss tells you which branch of the map to go back to.
- Read a mind map on one topic.
- Take a quiz on the same topic.
- Revisit the branches you got wrong.
- Use a flashcard deck such as Logic Gates, Binary & Hex for key terms.
Exams and where this sits
Many resources mention GCSE Computer Science, GCSE Computing, A-level Computer Science, National 5 Computing Science and other courses. Teachers can use the notes and decks as ready-made revision material. This unit is part of the Computer Systems strand in Computing and ICT.
Choose one resource that matches your course, work through it, and then make a map or deck of your own.
Frequently asked questions
Which resource should I open first?
Start with the mind map OCR Computer Science: Computer Systems, which sets out hardware and software with everyday examples. Then move to OCR GCSE Computer Science 1.1 for the CPU and its registers. Once you have read both, try the CPU and Memory quiz to see what stuck.
What do the mind maps cover?
They cover the CPU and its registers, RAM, ROM and cache, primary and secondary storage, input and output devices, operating systems, utility software and logic gates. There are also broader overview maps that put hardware, software and networking side by side, which suit a first look at a topic.
Are the resources free to use?
Yes. Every resource on this page is free to open, study and take, with no account needed. They were made by GoConqr users, not by GoConqr itself. If you want to save quiz scores or make your own quizzes, maps, flashcards and notes, you can add a free account.
Which exams do these resources suit?
The listed resources mention GCSE Computer Science, GCSE Computing, GCSE ICT, IGCSE ICT, A-level Computer Science, National 5 Computing Science, SQA Higher, BTEC IT and others. Most are at secondary level, so check the title and content against your own course before relying on it.
What if I can't find the topic I need?
Try a nearby resource first. Topics often overlap, so a map on primary storage or a deck of key terms may cover it. You can also build your own mind map or flashcards for the gap and keep them for later revision.
