सवाल

Which syllabus is covered?

The BTEUP Diploma Computer Science & Engineering Semester 4 Operating Systems syllabus. Where your college syllabus differs, the centre follows your own syllabus.

Are numericals included?

Yes. CPU scheduling, page replacement, Banker's algorithm and disk scheduling numericals are practised step by step.

Is Linux taught?

Basic Linux commands are shown to explain processes and files; the main focus is the theory needed for the exam.
