The subject acquaints the students with the basic principles of modern operating systems. Structure of operating systems is explained, functions of the individual components are described. Particular attention is paid to the parallel operation of processes, providing multitasking and multiuser work in any modern operating system. The problems that arise with simultaneous access of multiple processes to shared resources are presented. Classical methods and algorithms are addressed to solve these problems.
