• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

The operating system is much larger than what ROM can hold, so it lives on disk-based storage and is loaded into RAM to run. ROM is used for small, essential firmware that boots the system and initializes hardware, but it doesn’t provide the space or the flexibility to store and frequently update a full OS. Hard disks and SSDs offer the needed capacity and speed, plus easy updates, which is why the OS is stored there for most computing devices. There are some embedded systems where the OS resides in flash memory, but for typical PCs and laptops, the OS is stored on disk rather than in ROM.
