12 min read

RAM and ROM, secondary storage types, and system and application software.

Memory

  • RAM (Random Access Memory) — volatile (loses data when off); holds programs/data currently in use.
  • ROM (Read Only Memory) — non-volatile; holds the start-up instructions (e.g. the bootloader/BIOS).
  • Virtual memory uses storage as extra RAM when RAM is full.
