About memory and storage notes
GoConqr OriginalUsing Memory and Storage notes
For an introduction to storage devices, start with Storage and Magnetic Devices. It introduces storage devices and recording media, making it a useful starting point before you look at individual technologies.
For memory, the notes on RAM, ROM and virtual memory bring those topics together. You can also read the notes on RAM for more detail. Compare what each note says, then write a short summary in your own words.
Follow a storage topic
Secondary Storage covers storage that retains information when a computer is off. Other notes explore optical storage and flash memory, hard drive technology, and RAID. The XML & JSON notes cover formats for storing structured data.
After reading, use a mind map on the unit page if you want to organise related ideas visually. Switch to flashcards for short definitions or a quiz when you want to check what you remember. Pick a topic and try a different format alongside its notes.
Frequently asked questions
Which note is a good place to start?
Try Storage and Magnetic Devices if you want an introduction to storage devices and recording media. If your focus is memory, start with the notes on RAM, ROM and virtual memory instead. Both give you a topic to follow before moving to more specific notes.
What topics do these notes cover?
The notes cover RAM, ROM and virtual memory, as well as storage devices and technologies. You can also find notes on RAID, hard drives, optical storage and flash memory. XML & JSON looks at formats for storing structured data, offering another route through the page.
