Single mode only allows one user (root) to log into the system. This is usually for maintenance or emergency consoles. Almost none of the daemons are loaded and other filesystems may also not be mounted. The concept is similar to "safe mode" in Windows. It's not meant for regular use, but recovery or maintenance.
It is isn't a configuration difference to go between single user and multi-user modes in Unix. You use a different 'run' level for that. The 'init' levels can determine whether you are operating in a single user mode or a multiple user mode. Single user mode is usually reserved for system administration.
you go to control settings and press user , then it should have single user and then it says on/ and off and your press off !
Single user mode is designed primarily for systems administration. As such, the system will only load minimal drivers and processes necessary for that administration. Most disk partitions will not be loaded unless they are crucial to the administration of the system. Other users are not allowed to log in to the system in this mode. Multi-user mode is the normal mode of the system, with all resources available to users both locally and via the network.

The single user process is the environment that only 1 user may log into and use the system. Typically this is for the administrator account and is used only in recovery situations. It is vaguely similar to "safe mode" in Windows.
When you boot into single-user mode you aren't asked for any credentials (passwords, etc.). When you get the shell prompt, just reset the admin/root password using the passwd command. Then, allow multi-user mode to boot and you are all set with the new root password.
Reset your password using the verification method below:
The most graceful way is to use the command: init s If you want to shut everything down before going to single user mode then do init 0 first and from the ok prompt do a boot -s.
User mode
press any key while booting and then press e on booting line statement add 1 at the last and boot the computer.. you can also use "init 1" to boot in single user mode from running os..
/var shouldn't be strictly necessary, since, in single-user mode, there aren't going to be many daemons running, outputting logs, sockets, or PID files.
