About computer hardware and components notes
GoConqr OriginalComputer hardware and components notes
The notes on this page offer different routes through the unit. Input and Output Devices introduces devices used to provide data and control signals. GCSE Computing: Hardware covers the CPU, the fetch-execute cycle and processor characteristics. For memory, Chapter 7 RAM looks at types of RAM and basic troubleshooting.
Using notes to revise
A useful starting point is Input and Output Devices if you are reviewing how information enters a computer. For a closer look inside the machine, try Chapter 9 Motherboard, which covers expansion buses, installation and troubleshooting.
Read a section, then write down what you remember before checking the note again. Compare notes on the same topic when you want another explanation. If you want to test recall rather than read, switch to a quiz or flashcards on the unit page. Choose a topic and explore the notes that cover it.
Frequently asked questions
Which note is a good place to start?
Input and Output Devices is a useful starting point for reviewing how data and control signals enter a computer.
