Which memory type contains permanent instructions that guide core firmware and boot processes?

• A. RAM
• B. Software
• C. ROM
• D. Operating System (OS)

Answer: (C)

Permanent, unchanging instructions that guide the startup sequence are stored in ROM. Read-Only Memory is non-volatile, so its contents remain intact without power and hold the firmware that runs at boot. This firmware, like BIOS or UEFI, performs initial hardware checks, initializes devices, and locates the operating system on storage to boot the system. RAM cannot serve this role because it is volatile and loses its contents when power is removed, making it unsuitable for permanent boot instructions. Software and the operating system are sets of instructions that are loaded and executed after boot from storage and run in RAM, not in the firmware that must persist across power cycles.
