Which memory stores permanent startup instructions and helps initialize the BIOS?

• A. RAM
• B. Cache
• C. ROM
• D. Hard Drive

Answer: (C)

ROM stores the firmware that contains the permanent startup instructions. This non-volatile memory keeps its data when the power is off, so the system can boot even after a shutdown. At power-up, the BIOS or UEFI runs from this firmware to perform the initial hardware checks and initialize components, then it hands control over to the operating system loader. RAM, by contrast, is volatile and is used for active programs once the system is running. Cache is a tiny, ultra-fast area near the CPU for speeding data access, not for firmware. The hard drive holds the operating system and files, not the initial boot instructions themselves.
