Normally linux boots up in multi-user mode which mean that more than one user can be logged in to your computer at the same time.
In single-user mode only root user are allowed to log in. This is an administrative mode used when certain task are to be performed which demand total control of the system.
No other users can interfere with your work.

To go into single user mode if you are using lilo as your boot loader type linux single

0 - halt (Do NOT set initdefault to this.)
1 - Single user mode
2 - Multiuser, without NFS (The same as 3 if you do not have networking.)
3 - Full multiuser mode + Network
4 - unused
5 - X11 (Xwindows + network/Multiuser)
6 - reboot (Do NOT set initdefault to this.)

If your in runlevel 3 or 5 you can get to single user mode by typing "init 1" from a command line
