What this course is about Fundamental OS concepts OS: one of the most crucial, almost everything thru OS What? Functionality? How? Processes, threads, synchronization, scheduling, file systems … Many concepts wide use broad picture: how everything works together, hardware, programming language, algorithms … Hands on experience learning and hacking a real OS (Linux) Skills + concepts Probably your first course dealing with large software how to read, know, filter, modify, debug complex systems Team work
