This lecture continues and consolidates the topics of the basic course "Operating Systems and Security". The lecture covers scalability, fault tolerance, memory consistency and synchronization in parallel systems, security in distributed systems, and Trusted Computing.

In this course with a strong exercise and lab component, the focus is on building one's own simple operating system from scratch. For this purpose, we teach knowledge about the structure and functionality of PC hardware, but also recapitulate and deepen basics such as interrupts, synchronization and scheduling.

This lecture addresses the current development of 2nd-generation microkernels in a very practical manner. We start with a short introduction to the area of microkernel-based systems and then illustrate mechanisms of modern microkernels by means of example code and accompanied by practical exercises.

When designing a real-time system, a critical decision is how much computation time to assign to processes. This lecture teaches the basic terms, methods, and results of scheduling theory.
