About computer systems notes
GoConqr OriginalComputer Systems notes to start with
Start with Hardware and Software for a distinction between physical components and the programs that give them instructions. For a closer look at processors, GCSE Computing: Hardware includes the CPU and the fetch-execute cycle.
The notes also cover storage, input devices and data representation. Computing Revision introduces the fundamentals of computer systems, including reliability. You can move between these notes according to the topic you are studying.
Revise with notes
Read one set of notes, then write a short summary in your own words. Return to the original to check which terms or ideas you missed. For a topic such as secondary storage, compare your summary with the notes before moving on.
When you want to check your recall, switch to a quiz on the unit page. A mind map can help you organise the ideas you have just read. Pick a topic and open a set of notes.
Frequently asked questions
Which notes are a good starting point?
Hardware and Software is a useful starting point for the distinction between physical components and programs. If you are revising the CPU, GCSE Computing: Hardware covers that topic and the fetch-execute cycle. Computing Revision offers notes on the fundamentals of computer systems.
What topics do the notes cover?
The collection includes notes on hardware, software, computer systems and processors. There are also resources titled Secondary Storage, Input Devices And Media and Data Representation. Each set of notes focuses on its own topic, so you can choose one that matches what you are revising.
Are the notes free to use?
Yes. Every resource listed here is free to open and study without an account. The notes were made by GoConqr users. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
Who are these notes for?
The collection is mainly suited to school students revising computer systems and teachers looking for ready-made material. Some notes mention GCSE Computing, including GCSE Computing: Hardware. Teachers and students can choose notes on a particular topic, such as storage or data representation.
