Kurzfassung:

The module covers the functionality of modern operating systems. Based on the basic concept, the connection between the hardware of the computer system and interaction with the user is discussed. The focus is on the services that an operating system offers an application program or a user. In order to understand and assess these services, the most important principles and techniques of their implementation are presented. The main topics are: tasks and architecture of operating systems, device management and file systems, memory management, process management and parallel processes as well as process communication, security and command interpreters. Working with an operating system is taught in practical exercises.

Lernziele:

The participants develop a deeper understanding of the tasks, structure and functionality of an operating system. They explain the different subtasks of an operating system and compare the corresponding forms of implementation with regard to their advantages and disadvantages. On this basis, you can make well-founded design decisions for adapting an operating system to requirement profiles.
