They can do lots of different things within a circuit. Most notably is that they steady the voltage supply within a circuit. If and when the voltage drops, the capacitor releases some stored voltage and this stabilizes the signal.

They can also be used for a number of other components to create filters that remove certain frequencies, and in conjunction with resistors to create timing circuits (to name a couple).
