What is NVRAM/Boot ROM?

• A. Random access memory used for temporary data during boot.
• B. Non-volatile storage holding firmware that initializes hardware and starts the bootloader.
• C. A volatile cache that speeds up boot processes.
• D. A type of flash memory used for user data.

Answer: (B)

NVRAM/Boot ROM is non-volatile memory that stores the system firmware responsible for initializing hardware and starting the boot process. When the system powers on, code in this memory runs first to perform essential checks, configure hardware, and load the bootloader so the operating system can begin starting up. Because it’s non-volatile, this firmware stays intact without power, unlike RAM which loses data when power is removed. It isn’t used for temporary data, it isn’t a volatile cache, and it isn’t storage for user data.
