The course „Grundgebiete der Informatik 3 .- Betriebssysteme und Systemsicherheit“ (BS) gives a deeper understanding of modern computer architectures and its operating systems. Through this course the students learn the consequences of the software design and its implementation with respect to performance, portability, and security of the overall system. The course is divided into the following parts:
