In Linux perspective a system start up flow of control is as follows:
1. BIOS :- Performs basic power on test which initializes CPU, RAM, had disk, mouse, keyboard, video display etc.
2. Boot Loader :- Loads operating system and calls start_kernel().
3. Kernel :- Runs the first user-space program init().

init() is called the mother of all processes, since this calls all other processes.
