The subject of our interest is an educational process, which is a dynamic process, changing in time, and can be examined from various viewpoints. We can focus on participants of this process, i.e. on students and lecturers, and observe their mutual relations and interactions. Educational process understood as a dynamic system is an insofar extensive sphere that it provides almost limitless opportunities of observation, modelling and simulation. In this contribution we shall focus mainly on the special part of educational processes – on teaching of subjects focusing on technical and system issues (Logical systems, Architecture of computers, Operating systems and Computer networks), which are specific with their focus on adopting the knowledge on principles and functionality of computer systems for the processing and transfer of information within the studies of informatics.
