"volatile" indicates that the object is modified by something not directly under the compiler's control (i.e. the hardware itself, or another thread of control).   An example might be the global variable that keeps track of the total number of timer interrupts, or a hardware clock.

You should probably reject the answer I gave to the other version of this question.
