Which process starts a computer from a powered-down state?

• A. Hardware
• B. Boot Process
• C. Client
• D. Web Browser

Answer: (B)

Starting from a powered-down state is the boot process. When you press the power button, the system firmware initializes hardware, runs a power-on self-test, and locates a bootable device. It then loads the bootloader, which starts the operating system kernel in memory and hands control to the OS so the computer becomes ready for use. This sequence is specifically about turning the machine on and preparing it to run software, which is exactly what the boot process does. Other options refer to things that either describe the hardware itself or programs that run after the system is already on (a client, or a web browser), not the startup sequence from off.
