Bios — CompTIA A+ Core 1 (220-1101) Practice Questions
BIOS (Basic Input/Output System) is the legacy firmware interface stored on a chip on the motherboard that initializes hardware and hands control off to the operating system bootloader. It operates in 16-bit real mode, supports drives up to 2.2 TB using MBR partitioning, and presents a text-based configuration interface. The 220-1101 exam expects technicians to understand BIOS settings such as boot order, enabling or disabling integrated peripherals, and the role BIOS plays in the startup sequence before the OS loads.
