Which memory contains the diagnostic routines for boot up?

Explanation:
Boot-up diagnostic routines need to be available before any software runs, and they must survive power cycles. That’s why they’re stored in non-volatile memory that is read-only during normal operation. ROM holds the firmware that executes at power-on, including the POST (Power-On Self-Test) that checks hardware and initializes devices. RAM is volatile, so it would lose the code as soon as power is removed, which would make boot impossible. While flash memory can also store firmware and can be updated, the traditional place for those initial boot diagnostics is ROM. NVRAM stores small non-volatile data like BIOS settings, not the boot routines themselves.
