Operating System Principles, 7th Ed

Key themes

Resource Management

This theme explores how operating systems efficiently allocate and deallocate critical system resources such as the CPU, memory, and I/O devices among competing processes. It covers various strategies and algorithms for scheduling, allocation, and protection to ensure optimal performance and fairness.

Concurrency and Synchronization

This theme focuses on the challenges and solutions for managing multiple processes or threads that execute concurrently. It delves into issues like race conditions, deadlocks, and starvation, and introduces mechanisms such as semaphores, mutexes, and monitors to ensure data consistency and orderly execution.

Protection and Security

This theme addresses the mechanisms an operating system employs to protect system resources from unauthorized access and to secure the system against various threats. It covers access control, authentication, authorization, and the principles of secure system design, including defense-in-depth strategies.

Worth discussing

Discuss the trade-offs between different CPU scheduling algorithms (e.g., FCFS, SJF, Round Robin) in terms of fairness, throughput, and response time.
