Summary
Init is the parent of all Linux processes with a process ID of 1, and is the last step of the kernel boot sequence. It is responsible for initializing the system by creating processes from scripts stored in the file /etc/inittab, which are also called rc scripts. By default, most of LINUX based systems boots to runlevel 3 or 5, but users can modify the preset runlevels or create new ones according to their requirement.

In Unix-based computer operating systems, init (short for initialization) is the first process started during booting of the operating system. Init is a daemon process that continues running until the system is shut down. It is the direct or indirect ancestor of all other processes and automatically adopts all orphaned processes. Init is started by the kernel during the booting process; a kernel panic will occur if the kernel is unable to start it. Init is typically assigned process identifier 1.

A runlevel is a mode of operation in the computer operating systems that implements Unix System V-style initialization. Conventionally, seven runlevels exist, numbered from zero to six. S is sometimes used as a synonym for one of the levels. Only one runlevel is executed on startup; run levels are not executed one after another (i.e. only runlevel 2, 3, or 4 is executed, not more of them sequentially or in any other order).
