The sbin directories contains programs which are generally system administration only. Programs for regular users should never go in them.

A few programs are needed during startup, and end up in /bin/ or /sbin/. These must be available before files systems are mounted. Things like mount, and fsck that are required to check and mount files systems must be there.

Most packaged programs end up in /usr/bin/ and /usr/sbin/. These may be on a file system other than the root file system. In some cases they may be on a network mounted drive.

Local programs and scripts belong in /usr/local/bin/ and /usr/local/sbin/. This identifies them as clearly non-standard, and possibly only available on site.

For further explanation try running the command man hier which should provide a description of the recommended file system hierarchy for your distribution. You may also want to read about the File System Hierarchy on Wikipedia
