The Operating Systems course introduces the fundamental principles of an operating system. The course starts with a brief overview of operating system history and then covers major components and algorithms of most modern operating systems. Students learn critical design issues and their trade-offs in designing and implementing an operating system. Emphasis is placed on process management, concurrency, memory management, persistence, and security in an operating system. The course combines understanding theoretical concepts of operating systems and their hands-on implementation using a multithreaded programming library.
