In this paper the author reviews some facts from the theory of the characteristic classes and continuous cohomoloy. Namely, he shows how the continuous cohomology of a group measures the global informations needed to bring the infinitesimal computations (concerning the characteristic classes) into line with the global ones. The author considers only the finite dimensional case and gives an interesting example from the infinite dimensional case.
