variable resistor vs. voltage divider

  1. I have noticed that the only difference between a potentiometer wired as
    a variable resistor, and a potentiometer wired as a voltage divider, is
    that one terminal is either left unconnected or is connected to ground.
    But what is the actual difference in the wiper (output) signal between a
    variable resistor and a voltage divider? is it just that a variable
    resistor will never reach 0V, or is there more to it? thanks!
