maybe you can found answer in here
based answer on that link, this is the summary:
/bin
contains commands that may be used by both the system administrator and by users, but which are required when no other filesystems are mounted (e.g. in single user mode). It may also contain commands which are used indirectly by scripts
/usr/bin/
This is the primary directory of executable commands on the system.
