So just to clarify perhaps, the significance of that leading / is it refers to the root partition. So no matter what directory you are in a reference to /usr/bin/ will always go to exactly the same place - /usr/bin/. A reference to usr/bin/ is relative to your current directory, so if you are in /home/ then it will go to /home/usr/bin/ (if it exists) or if you are in /var/ then it will go to /var/usr/bin/ or if you are in /tmp/ it will got to /tmp/usr/bin/ and so on.
