The playlist starts from first principles: what an OS does, user mode versus kernel mode, system calls and the main OS components. It then covers the structural designs an operating system can take, including simple, layered, monolithic, microkernel, modular and hybrid.
Later videos move through processes and PCBs, multithreading, CPU scheduling algorithms such as FCFS, SJF, priority, round robin and multilevel queues, and process synchronization with semaphores, mutexes and monitors. Deadlock, memory management, file systems, disk scheduling and I/O systems close the list.
