What is a decoupling capacitor and how do I know if I need one?

The bulk (polarized) tantalum capacitors are only for lower frequency because they are "slow" (due to ESR -- think small RC filter inside the capacitor). When people say "smoothing" capacitor I think more of the bulk capacitance on the output of a power supply, not decoupling at the power pins.
