Where do todays computers store almost all motherboards configuratuion data?

Today's computers store almost all motherboard configuration data in a non-volatile memory called the BiOS (Basic Input/Output System) or UEFI (Unified Extensible Firmware Interface). This memory retains settings even when the computer is powered off, allowing the system to boot and configure hardware components upon startup. The configuration data includes system settings such as boot order, hardware settings, and system time.
