Operating Systems

Key themes

Process Management

This theme explores how operating systems manage processes and threads, which are the fundamental units of execution. It covers process creation, termination, states, inter-process communication, and various scheduling algorithms (e.g., FCFS, SJF, Round Robin, priority-based) that determine how CPU time is allocated among competing processes.

Memory Management

This theme delves into how the operating system allocates and manages the main memory (RAM) for various processes. Key concepts include virtual memory, paging, segmentation, swapping, and memory protection mechanisms. It addresses challenges like fragmentation and ensures efficient use of limited physical memory resources.

File Systems and Storage Management

This theme covers how the operating system organizes, stores, retrieves, and protects data on secondary storage devices (e.g., hard drives, SSDs). It includes topics like file structures, directory structures, allocation methods (contiguous, linked, indexed), free-space management, and disk scheduling algorithms.

Worth discussing

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