'''Noise''' is a term for distortions in a [[signal]]; there are many different natural causes of noise, e.g. so-called 'thermal' noise, caused by the random motion of [[electron]]s in the [[conductor]]s of a [[circuit]], noise from natural phenomena such as lightning, solar radiation, etc.

'''Interference''' is the term for the subset of noise which is not natural, but comes from other electrical systems; e.g. [[crosstalk]], or noise from industrial sources such a car ignitions.

 Noise can occasionally be useful, e.g. as input to a [[random number generator]].
