Questions

Which syllabus does this Operating Systems course follow?

It follows the common UP state university BCA syllabus (University of Lucknow pattern) for BCA Semester 4. If your own university's syllabus differs, the centre follows your university's syllabus and unit order.

Are numericals asked?

Yes - CPU scheduling (waiting and turnaround time), Banker's algorithm, page replacement and disk scheduling.

Is Linux taught practically?

Yes. Linux commands and shell scripts are practised in the Computer Graphics and OS Lab.
