Korshub's take

What the video covers

This is one long lecture of about 16 hours that works through core operating systems topics in turn, from how a machine boots to virtual memory and thrashing. Its timestamps group the material into processes and threads, CPU scheduling, concurrency, deadlocks, memory management and file systems.

Scheduling and concurrency

A large share of the running time goes to scheduling algorithms and synchronization problems such as producer-consumer and the dining philosophers. Deadlock avoidance, detection and recovery follow, and several segments work through concurrency problems as exercises.

Who it suits

Students preparing for placement interviews, since the title frames the video that way.
Anyone revising paging, segmentation and page replacement before an exam.
