Operating Systems

Semestr: Summer

Range: 2+2s


Credits: 5

Programme type: Undefined

Study form: Fulltime

Course language:


The course is an introduction into the classical theory of operating systems (OS). Students learn about basic notions, such as processes and threads and their communication, scheduling algorithms, race conditions, critical sections and synchronization problems and mechanisms, process deadlock, virtual memory using paging or segmentation, management of I/O devices, file systems and finally the basic issues of security. Experience with programming in the C language is expected.


Operating system, process, thread, deadlock, synchronization, memory, filesystem.

Course syllabus:

1. Introduction to OS. Architecture and types of OSs.
2. Processes and threads, their implementation. Scheduling algorithms.
3. Interprocess communication (IPC) - race conditions, critical sections, synchronization mechanisms.
4. Classical IPC problems - definitions and solutions.
5. Deadlock - definition, Coffman's conditions, strategies for dealing with deadlock.
6. Memory management - basic techniques.
7. Virtual memory - paging.
8. Virtual memory - page replacement algorithms.
9. Virtual memory - segmentation. Swapping.
10.Input/output - drivers of peripheral devices.
11.Files systems.
12.Distributed computation, client/server, clusters.
13.Security in OS.
