Some aspects of the characterization of the "complexity" problem are reviewed, in particular for the two ubiquitous dichotomies chaos-noise and discete-continuous.

A special attention is devoted to finite-resolution effects on predictability. The problems involved in systems with intrinsic randomness is discussed, with emphasis on the important problems of distinguishing chaos from noise and of modeling the system.

We show that the practical difficulties in the distinction chaos from noise and of modeling the system, has a positive role in the problem of generation of Pseudo Random Numbers and the approximation of continuous system as discrete states automata.
