What is a primary function of the system BIOS?

• A. Manage system processes
• B. Load operating system
• C. Interface with external devices
• D. Provide real-time clock functionality

Answer: (B)

The primary function of the system BIOS (Basic Input/Output System) is to load the operating system. When a computer is powered on, the BIOS is the first firmware that runs, performing essential tasks such as hardware initialization and self-test routines. Following these tests, it locates the operating system on the storage device (like a hard drive or SSD) and loads it into memory to begin the boot process. This action sets up the platform for the operating system to function effectively. While the BIOS does interface with external devices and may provide functionalities related to system processes and real-time clock operations, its core purpose centers around the booting sequence and loading the operating system, making that answer the most fitting in this context.
