   The superficial nature of the presented approach to the classification of computers is obvious. It is typically used only to describe the general features of the most common computing devices. The rapid development of computer technology means constant expansion of its applications and the rapid obsolescence of the concepts. For a more rigorous description of features of a computer is usually required to use other classification schemes.
