Describing the UNIX System in a strictly linear fashion, without any forward references to terms that haven't been described yet, is nearly impossible (and would probably be boring). This chapter provides a whirlwind tour of the UNIX System from a programmer's perspective. The boot process is usually initialized when a user presses the power-on button - if the PC was already shut down - or reboots the system using either the The booting process ends once systemd loads all the daemons and sets the target or run level value.

A lot of the advantages of Linux are a consequence of Linux' origins, deeply rooted in UNIX, except for the first advantage, of course: • Linux is free 1973 Unix is re-written mostly in C, a new language developed by Dennis Ritchie. Being written in this high-level language greatly decreased the effort needed to port it The operating system, referred to in Unix as the kernel, interacts directly with the hardware and provides the services to the user programs. Unix grew out of Multics, a failed multiuser operating system project in which Bell Laboratories was involved.With the Multics project terminated, members of Bell Labora-tories' Computer Sciences Research Center found themselves without a capable interac-tive operating system. A UNIX operating system consists of a kernel and some system programs.

Yeah, as a SysAdmin, it's very important to know about the steps and the processes in every steps while a machine boots up. If you are a good SysAdmin, you must have a better knowledge in Booting Process.
