Final answer:
CMOS is the term that refers to a semiconductor used to store BIOS settings, which can change when hardware is added or removed, unlike ROM.
Step-by-step explanation:
The term you're referring to is CMOS (Complementary Metal-Oxide Semiconductor). CMOS is similar to ROM (Read-Only Memory) in that it stores firmware or BIOS settings for computers. However, unlike ROM, which is non-volatile and doesn't change unless it is flashed or updated in a special process, the CMOS settings can change. Whenever you add or remove hardware from your computer, the CMOS settings may be updated to reflect these changes, like configuring the boot order or enabling and disabling onboard peripherals. The CMOS is powered by a small CMOS battery on the motherboard that ensures settings are retained even when the computer is turned off or unplugged.
