Operating Systems and Security

We're currently conducting a survey to get some feedback on the lecture in general and its exam in particular. Participation is voluntary but would help us to improve the lecture. The questions are in German but answering in English is also fine.
You can review your exam results on Thursday, 27th September from 16:00 to 17:00 in room APB 3105 . Please bring your student card and any identity card with a photograph. Individual appointments are not necessary. Even though a registration is not required, you may want to preregister to reduce your waiting time. If you are unable to attend on this date for important reasons please send an e-mail to Jan Bierbaum as soon as possible.


The lecture introduces the fundamentals of systems architecture. Students learn the key building blocks and construction principles for local systems first and for distributed systems later on. A primary concern for us is to highlight references to neighboring topics. Examples are discussing the interaction of certain hardware characteristics with system building blocks, the introduction to the basics of cryptographic techiques and the application of mathematical methods to ascertain quantitative properties of systems. We also focus on some principles for constructing fault-tolerant and secure systems already in this basic course. A third concern is to get students acquainted with techniques for low-level machine-oriented programming at the latest in this lecture.
