Operating Systems
Explore how operating systems manage hardware, run applications, and keep systems secure and stable. These quizzes cover core concepts like processes, memory, filesystems, and scheduling, with practical questions that connect theory to real computing scenarios.
Quizzes
Process scheduling: FCFS, SJF, and RR
Test your understanding of CPU scheduling with FCFS, SJF, and Round Robin. Work through realistic scenarios involving arrival times, burst times, and time quantum to predict execution order and key metrics. With mixed difficulty, it’s a solid refresher for OS exams and interviews.
Virtual memory: paging and TLB basics
Build confidence with the core ideas behind virtual memory, paging, and the TLB. You’ll work through address translation, page tables, and common performance concepts using practical, exam-style scenarios. Choose your preferred length and difficulty, then learn from each question as you go.
File systems: inodes, paths, and permissions
Explore how Unix-like file systems really work, from inodes and directory entries to absolute/relative paths and permission bits. This mixed-difficulty quiz helps you connect command output to underlying structures and avoid common mistakes with ownership, modes, and traversal rules. Choose your preferred question count and difficulty, then learn through clear, practical scenarios.

What you’ll practice
These Operating Systems quizzes help you review the building blocks behind modern computing, from process management and threads to memory, storage, and device I/O.
You’ll also practice reading scenarios (like deadlocks or paging behavior) and choosing the best explanation or next step based on OS principles.
How the quizzes work
Each question has 4 answer options and there’s no timer, so you can focus on accuracy and understanding rather than speed.
Quiz length and difficulty vary across the set, letting you start with fundamentals and move toward more detailed, system-level topics as you improve.
Topics you’ll see
- Processes vs. threads, context switching, and CPU scheduling
- Virtual memory, paging, segmentation, and page replacement
- Synchronization, race conditions, and deadlocks
- Filesystems, permissions, and storage concepts
- System calls, kernels, and user vs. kernel mode
- I/O, interrupts, buffering, and device management
Quick OS context
Operating systems evolved from early batch systems into time-sharing and multitasking platforms, enabling multiple users and programs to share limited CPU and memory efficiently.
Many modern OS ideas—like virtual memory and protection rings—were designed to improve both reliability and security while keeping performance acceptable on real hardware.
