Runlevels

Runlevels define what tasks can be accomplished in the current state (or runlevel) of a Linux system. Every Linux system supports seven  runlevels in the Red Hat Linux Operating system .

Run level               Working

0                          Shut Down (or halt )
1                        Single user mode ; usually aliased s  or S

2                         Multiuser mode without  networking

3                         Multiuser mode with networking

4                        unused

5                        Multiuser mode with networking and X windows system

6                    reboot the system

we are change the run level in the file of inittab.
  syntax :- # vim /etc/inittab
Then edit the run level if you want
