Options of GPSS World for integrated demonstration models in the educational process

The advantages of the simulation modeling imply its use in the training of students in different disciplines. This paper provides various simulation models of algorithms that operate on different systems: computer systems, computer networks, database management systems and operation systems. These models can be used to demonstrate how the quoted systems work, in teaching on the disciplines accordingly Computer architectures, Computer networks and communications, Database systems and applications and Operation systems. One of the classic systems of simulation modeling GPSS World provides software tools and environment for the development of an innovative approach with practical character, to demonstrate and visualize the working algorithms of the quoted systems.
