Explore process synchronization in operating systems, learn how concurrent access to shared data causes data inconsistency and race conditions, and preview the critical section problem with practical examples.
Analyze how semaphores coordinate a bounded buffer by the producer–consumer interaction, using empty and full slots with mutex protection to manage slot availability and data transfer.
Explore a hardware-based test and set mechanism for process synchronization, using a lock variable to control entry to the critical section between two processes P1 and P2.
Explore the dining philosopher problem solved with monitors, featuring enum thinking, hungry, and eating. See how the self condition delays hungry philosophers and coordinates pick up and put down.
Learn priority scheduling, where the highest priority runs, aging prevents starvation, and both non-preemptive and preemptive versions are illustrated with a process example and a Gantt chart.
Explore multilevel feedback queue scheduling, which moves processes between three queues based on cpu burst, uses 8 ms and 16 ms round-robin, and fcfs, with aging to prevent starvation.
Virtual memory is a memory management technique that lets programs run larger than physical memory by separating logical and physical memory, using a page table and translation lookaside buffer.
Explore the least frequently used page replacement algorithm, a counting-based method that tracks reference frequencies, increments on access, and decrements on eviction. Tie-breaks rely on fifo, with hits and faults.
Explore thrashing by high multiprogramming and lack of frames, and how page faults swap between memory and secondary memory, affecting cpu utilization, with working set and page fault frequency models.
Explore disk scheduling and IO scheduling algorithms, including FCFS, SSTF, scan, c-scan, and look, to optimize disk access time and minimize seek delays.
Explore the C-look disk scheduling algorithm, its left-to-right head movement, stopping at the last request, and how it reduces delay versus SCAN and C-SCAN.
This course offers a comprehensive introduction to fundamental operating system concepts, focusing on key areas like process synchronization, scheduling, memory management, and disk handling. You will gain an in-depth understanding of synchronization techniques such as the Bounded Buffer Problem, Peterson’s Solution, Mutex Locks, Semaphores, and the Reader-Writer Problem, which are critical for managing the coordination between multiple processes. The course also covers a wide range of scheduling approaches, including thread scheduling, real-time CPU scheduling, and multi-processor scheduling, all aimed at optimizing CPU resource allocation for better performance.
In addition to process management, you’ll dive into deadlock handling, learning methods to detect, prevent, and recover from deadlocks, ensuring system stability and efficiency. The course covers essential memory management techniques like swapping, segmentation, paging, and virtual memory, which are critical for efficient data handling. Practical strategies for implementing page replacement policies and avoiding thrashing are explored, giving you the tools to manage memory allocation effectively in high-demand situations.
Disk management is another major focus of the course, where you’ll learn about disk scheduling algorithms, RAID structures, and file system organization. The course emphasizes important aspects of file sharing and protection mechanisms to ensure secure and efficient file access and management.
By the end of the course, you will have developed the skills and knowledge needed to tackle real-world operating system challenges. Whether you are a professional, developer, or a tech enthusiast, this course is ideal for those seeking to deepen their understanding of operating systems.
