Learning outcomes of the course unit

Complex overview with all the related aspects of solving access and transport networks and their devices, especially with reference to prospective solutions of integrating networks and services. Network viewed as the largest cybernetic machine in the world and controlled from the terminal equipment. Processes of this control, as well as its organization, make it possible to get to the roots of control. Applying this knowledge, especially of control organization, also to other areas of economic and social life.
