Distributed Systems Exam Materials
Course Introduction
This course explores the fundamental principles and practical aspects of distributed systems, where computing resources are spread across multiple networked computers that collaborate toward a common goal. Students will examine key topics such as system architectures, communication protocols, synchronization, fault tolerance, consistency, transparency, security, and scalability. Through case studies and practical exercises, learners gain insights into building and managing reliable, efficient, and secure distributed applications, understanding challenges unique to distributed environments, and employing modern frameworks like cloud computing, peer-to-peer networks, and distributed databases.
