Which chip stores the settings in the BIOS?

• A. Real Time Clock (RTC), Non-volatile RAM (NVRAM)
• B. Complementary Metal-Oxide Semiconductor
• C. Central Processing Unit
• D. BIOS ROM

Answer: (A)

BIOS settings are kept in a small non-volatile memory area called CMOS RAM. This memory holds the configuration options (boot order, date/time, device settings, etc.) and is battery-powered so its contents survive when the computer is turned off. The Real-Time Clock circuit provides the timing functions and, with the battery, keeps the CMOS RAM alive. So the storage of BIOS configuration is best described as non-volatile RAM under the RTC, which is why the option that pairs RTC with NVRAM fits. The BIOS firmware itself lives in ROM, not the settings.
