Final answer:
Today's computers store almost all motherboard configuration data in CMOS RAM.
Step-by-step explanation:
Almost all motherboard configuration data in today's computers is stored in CMOS RAM (Complementary Metal-Oxide-Semiconductor Random Access Memory).
CMOS RAM is a type of memory that is powered by a small battery on the motherboard, allowing it to retain data even when the computer is turned off.
It stores information such as date and time settings, system configuration settings, and BIOS settings.
