After successful completion of the course, students are able to describe the role and the functions of operating systems, judge design decisions for the management of OS resources, use mechanisms for the coordination of and the synchronization between parallel processes, and elaborat on OS security mechanisms.

• introduction to operating systems (definition, history, important abstractions, OS architectures)
• processes and threads (process states, data structures and mechanisms for process management, multithreading)
• process synchronization and deadlock (mutual exclusion & condition synchronization, synchronization mechanisms and constructs, synchronization problems: producer-consumer, reader-writer, dining philosophers, deadlock, deadlock conditions, deadlock avoidance, deadlock prevention, deadlock detection
• memory management (allocation, relocation, segmentation, paging, virtual memory management, page replacement, protection and sharing)
• input-output and disk management (devices and device characteristics, I/O operations, drivers, buffering, disks, file systems, file system organization)
• networking (introduction, protocols, OS and networking)
• security and protection (threats, security measures, design for security, access control, authentification, encryoption)

The listed topics will be introduced in the lecture, illustrative examples will be presented. Selected programming problems will be assigned in the accompanying lab course.

ECTS breakdown: 2 ECTS = 50 hours; 24h attendance of lecture, 24h preparation for lecture, postprocessing of lecture, preparation for exam, 2h exam

Students can attend the lecture in the lecture room or follow the live stream via the LectureTube (links in TUWEL). Recordings of the lectures and presentation slides will be made available on TUWEL.

We will offer written and oral exams at TU, provided the Covid-19 rules will allow for that. Otherwise, exams will be held as oral online exams via Zoom.
