Memory management, hardware management, process administration and interprocess communication are central areas of operating systems. The concepts and principles on which classical and modern operating systems are based are explained by the author using relevant tasks and solutions. The work thus provides a comprehensible introduction to the architecture of operating systems and is therefore also suitable for teaching in the bachelor's program. Uniquely, the book presents all content bilingually: in two columns, the German and English texts appear side by side, so that readers can improve their language skills and vocabulary at the same time.
