Correct Answer:
C. Run POST and boot computer
The BIOS (Basic Input/Output System) is a critical piece of firmware stored on a ROM (Read-Only Memory) chip on a computer's motherboard. It's the very first software that executes when you power on your computer.
- The correct answer is Run POST and boot computer. The primary function of the BIOS is to perform the Power-On Self-Test (POST), which checks if essential hardware components (like RAM, keyboard, and storage drives) are present and functioning correctly. After a successful POST, the BIOS locates and loads the operating system from a storage device into the computer's RAM, initiating the boot process.
- Perform calculations is incorrect; this is the role of the CPU and application software.
- Manage internet connections is incorrect; this task is handled by the operating system and network drivers.
- Store user files is incorrect; user files are stored on long-term storage devices like hard drives or SSDs, not the small, non-volatile memory of the BIOS chip.
