Content
The lecture introduces the fundamentals of systems architecture. Students will 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 techniques 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.
Breakdown of the lecture:
- Introduction
- Key Building Blocks
- UNIX
- Processes and Threads
- Deadlocks
- Security
- Memory
- Quantitative Methods
- Client-Server-Architectures and Process-Communication in Distributed Systems
- Security in Distributed Systems
- File Systems
- Distributed File Systems
- Fault-Tolerance
- Device Drivers
Organisation
Due to the still ongoing Corona situation in Germany, the lecture will take place this semester as an online event. The lectures for both parts of the module (Operating systems and Security) will be held as online lectures with additional recordings. The exercises will also be held this semester as online exercises with occasional videos as support material.

Exercises
You can enroll for the exercises starting Monday, October 11th via JExam. In case sessions get too crowded, the enrollment is binding. Please distribute to ensure the best possible experience. The exercises start in the second week of the semester (the week starting at October 18th) and will be held as online exercises.
Some of our exercise tasks require a unix-like system. If you are not using one yourself, we provide here a description on how to setup and mantain one such system.
