Are you interested in learning the basics of operating system concepts? Are you a student from a university such as IGNOU, or a mature student with a busy schedule? Look no further, because this course is designed with you in mind!
In this course, we will cover the important topics, concepts, and questions asked in the previous few IGNOU term-end examination papers. Let’s dive into what you can expect.
First things first, what is an operating system? We’ll cover examples such as DOS, Unix, Windows, and Macintosh. We’ll also explore the generations of operating systems and the types of operating systems.
We’ll discuss the various functions of operating systems, including process management, memory management, and file management. We’ll also explore the different process states and the implementation of processes, as well as context switching and threads.
What is a scheduler, you ask? We’ll cover that too! From there, we’ll delve into the different types of schedulers, including long-term, short-term, and medium-term schedulers. We’ll also cover scheduling algorithms like preemptive scheduling, non-preemptive scheduling, First Come First Serve (FCFS), Shortest Job First (SJF), Round Robin (RR), Shortest Remaining Time Next (SRTN), and Priority Based Scheduling or Event-Driven (ED) Scheduling.
We’ll explore interprocess communication and synchronization, including shared-memory systems, message-passing systems, and critical sections. We’ll cover the Mutex Solution, Mutual Exclusion, Bakery’s Algorithm, and Classical Problems in Concurrent Programming like the Producers/Consumers Problem, Locks, and Deadlocks.
In this section, we’ll cover memory management techniques like overlays, swapping, paging, and virtual memory. We’ll also discuss ways to avoid thrashing, such as the Working-Set Model and Page-Fault Rate.
Finally, we’ll dive into I/O file management, RAID, and security models like the Bell and La-padula model.
