Question

Which of the following locations stores the boot sequence for a desktop computer?

Options

ABIOS
BTPM
CCPU
DBoot sector

Explanation

The BIOS (Basic Input/Output System) - or its modern successor UEFI - stores the boot sequence configuration, which defines the order in which the system checks devices (e.g., hard drive, USB, optical drive) for a bootable OS. This setting is persistent and stored in non-volatile memory (CMOS chip backed by a battery). The TPM (B) (Trusted Platform Module) handles cryptographic functions and secure boot verification, not boot order configuration. The CPU (C) executes instructions but does not store configuration data. The boot sector (D) is a region on a storage device that contains the initial bootloader code - it's read by the BIOS, not the other way around.
