The aim of the course is to provide introductory knowledge on selected topics in the field of distributed computer systems. Students will be introduced to state-of-the-art distributed system architectures with a special focus on the inter-process communications (IPC) in distributed computer systems. Students will learn and acquire a deeper understanding of the challenges and approaches in designing distributed computer systems and with the provided assignments they will be trained to developed practical skills for implementing client-server-based distributed applications using the current IPC technologies.
