What is the main responsibility of the__________in configuring hardware and loading the OS?
Show answer Hide answer
Answer: B. BIOS
Explanation
The Basic Input/Output System initializes hardware components during the initial computer boot sequence. It locates and loads the operating system kernel from secondary storage into primary memory. Without the BIOS firmware, a computer would not know how to test its memory or start up. The BIOS is traditionally stored on a non-volatile flash memory chip located on the motherboard. Modern computers are increasingly replacing traditional BIOS firmware with unified extensible firmware interfaces. During startup, the power-on self-test verifies that all essential hardware components function correctly.
IT technicians access the BIOS setup utility to change boot device priorities and hardware settings. Upgrading computer hardware sometimes requires updating the motherboard BIOS version for compatibility. Understanding the boot process helps troubleshoot computers that fail to start up properly. System programs are general operating software applications running on top of the loaded kernel. CP refers to central processing, which depends on firmware initialization to begin functioning. Memory provides volatile temporary storage but requires hardware initialization controllers to operate.
