CPU strength up and looks to the BIOS (Basic input calculation system), the is save on a ROM chip, because that instructions.

BIOS runs post (power on me test) testing itself, CMOS RAM, CPU, connecting gadgets like keyboard and mouse.
BIOS describes CMOS ram to work-related out where the Operating device (Like Windows) is. CMOS looks at the computer system boot sequence to discover the correct journey (Hard drive, Optical, USB thumb drive) to run the operating system.
The BIOS check the hard drive because that the boots strap loader, situated in the first sector that the difficult drive.
The boots strap loader looks for the operating mechanism on the difficult drive and begins loading the operating device that is found, favor Windows or macOS.
As the Operating mechanism starts, BIOS duplicates its files (from the boot drive) into RAM and the OS takes control of booting the computer
The OS determines memory (RAM) available and loads hardware machine drivers to manage keyboard, mouse, etc.
The mechanism is prepared to use. The user have the right to run applications come perform required tasks. Applications are replicated from the boots drive right into RAM for much faster operation.
A identified sequence of steps that starts up the computer from turning on the power button to loading the operating system into RAM.
Forcing a computer to rotate on/off without letting the OS effectively shutting down. Can cause lost of files and also the system to obtain corrupt.
