What device runs the start-up instructions during boot-up of the computer?

Explanation:
Startup instructions are executed by the firmware stored on the motherboard, commonly called BIOS (or UEFI in modern systems). When power is applied, the CPU begins by running code from this firmware. That code performs the Power-On Self-Test, initializes essential hardware, and then locates a bootable device to load the operating system. RAM and GPU are not responsible for starting the boot process; RAM is used after boot, and the GPU handles graphics once the OS is running. So the element that initiates boot and hands control to the OS is the BIOS/UEFI firmware on the motherboard.
