The first process created in Unix at boot time is init whose process id is 1.It is the parent of all the process which runs till the system is shut down. Init process is responsible for starting other background process which is needed for operating system to function properly.For example httpd,tftpd,sshd etc.
Init is basically a daemon process which runs other process as daemons.All the daemon scripts are stored in /etc/init.d or /usr/lib/systemd/system that depends upon the linux distribution.
If a child process gets orphaned, automatically init process adopt it and become the parent process of it.
