STDERR is the standard output for error messages.
Normally if you have a script or program write to the screen, it would be something like STDOUT. STDERR is where programmers usually send log, error, or debug info to, and usually have STDOUT point to a special location.
If it isn't specified, STDOUT will go to the user's screen just like STDOUT does.
I hope this is what you were looking for.
