The BIOS in a standard PC is stored in _____?

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

Answer: (B)

BIOS is firmware that must persist without power, so it lives in non-volatile memory on the motherboard. Traditionally that means ROM (Read-Only Memory), and on modern boards it’s stored in flash memory that can be updated, but it remains non-volatile. RAM is volatile and loses its contents when power is removed, so it can’t hold BIOS. Cache is just a small, fast scratchpad for the CPU, not used for system firmware. A hard drive stores data and programs, not the boot firmware that runs before the OS. So the BIOS resides in non-volatile memory like ROM/flash on the motherboard.
