CS2850: Operating Systems (CS2850)

My study notes for the whole CS2850 module that took place at Royal Holloway, University of London. This is for the theory part of it - with topics including Processes and Threads, IPC with and without busy waiting, CPU scheduling, Interactive System Scheduling, and all taught algorithms related to both types of scheduling. Further to this there is memory management, virtual memory (MMU), page replacement algorithms, page faults, and file systems. Week 10 and 11 not covered.

Details problems that are common in IPC and multiple ways we can fix them with and without busy waiting. Details: Lock Variables, Strict Alternation, Peterson Algorithm, Test and Set Lock, Sleep and Wakeup, Semaphores, Mutexes, Monitors, Barriers and Read-Copy-Update.
