📚 About this Post:
This blog post includes all the important resources for the Operating Systems (OS) module – CSC61504. I’ve added key topics we covered during the semester, important points from our group projects, and some QnAs from our final exam (the ones I could remember). This should be helpful whether you’re doing last-minute revision or just trying to get a quick overview of the subject.

Final Exam QnA – Operating System (OS) 💻🔥

Since our college doesn’t give the question paper after the exam, these are the questions I remember from the final OS exam. Not all are here, but I noted down what I could recall. Hope it helps anyone preparing!

1. How does SSTF (Shortest Seek Time First) help reduce seeking time in disk scheduling?

2. Comparison of static and dynamic memory allocation by comparing their advantages and limitations.

3. How does the page table handle page faults and help in virtual memory?

4. One numerical from Banker’s Algorithm.

5. One numerical from Round Robin scheduling.

6. Types of Page Replacement Algorithms.

7. How does file management help in data security in a multi-user system?

This is also lists the important topics you should definitely focus on for your exam.
