Final answer:
BIOS programs that enable hardware to function are known as device drivers. The BIOS itself initializes the system, but the device drivers provide the interface between the operating system and the hardware.
Step-by-step explanation:
The BIOS programs that enable hardware to function are called device drivers. The BIOS, which stands for Basic Input/Output System, is firmware that is built into the computer's motherboard and is the first software that a computer runs when it is powered on. The primary purpose of the BIOS is to initialize and test the system hardware components, and to load a boot loader or an operating system from a mass memory device. It does not directly provide services to hardware; instead, device drivers, which are system software, function as the interface between the operating system and the hardware devices. Option A, POST, refers to Power-On Self Test, which is a diagnostic testing sequence that a computer's BIOS performs to check the correct operation of all connected hardware. Option B, services, usually refers to background processes in an operating system, and Option C, CMOS, stands for Complementary Metal-Oxide-Semiconductor, which is a battery-powered semiconductor chip inside computers that stores information such as the system time and system settings for the BIOS.
