Operating System

This page collects 125 operating system questions taken from 5 BEU semester 5 papers, 2019 to 2025 — about 25 questions in a typical paper. They are sorted into the 6 modules of the syllabus, so you can revise a topic across every year at once instead of working through papers one at a time. 125 of them have a worked solution.

What these papers actually ask

Module 2: Processes & Scheduling is the heaviest module in this archive at 28% of every question recorded, and it has come up in all 5 papers. Together with Module 5: Memory Management, the two account for 55% of the archive.

5 modules have appeared in all 5 papers — Module 2: Processes & Scheduling, Module 5: Memory Management, Module 6: I/O & File Management, Module 4: Deadlocks, Module 3: Inter-process Communication. A module that turns up every year is a safer use of revision time than one with the same question count concentrated in a single paper.
