The BIOS also manages essential functions like:

• Booting Process: The BIOS determines the order in which your computer checks for bootable devices (like hard drives, USB drives, or network connections) and loads the operating system.
• Hardware Configuration: It configures and manages basic hardware settings like the time and date, keyboard and mouse behavior, and boot options.
• Security Features: The BIOS includes security features like password protection, boot order control, and secure boot settings.
