Operating System – 105 MCQ Online Quiz
DSSSB TGT Computer Science Operating System practice test covering Process Management, CPU Scheduling, Synchronization, Deadlocks, Memory Management, Paging, Segmentation, Virtual Memory, Disk Scheduling, File Systems, Linux and OS fundamentals.
Operating System for DSSSB TGT Computer Science
Operating System is one of the high-value areas of Computer Science for DSSSB TGT preparation. The syllabus includes operating-system fundamentals, process management, CPU scheduling, synchronization, deadlocks, memory management, paging, segmentation, disk scheduling, file management and Linux/Unix-related concepts.
Available DSSSB TGT Computer Science paper collections include previous examination cycles such as 2018, 2021, 2023 and 2024. The 2023 cycle also had multiple shifts, so candidates should study concepts rather than depend only on memorising one paper.
The PYQ labels in this quiz indicate a previous-paper/topic trend. They do not claim that every practice question below was reproduced word-for-word in the listed year. Exact frequency can vary between shifts and paper sets.

Answers & Detailed Explanations
Frequently Asked Questions – DSSSB TGT Operating System
How many Operating System questions should I practice?
Candidates should practise a large variety of questions because DSSSB can test the same concept using different wording. This quiz contains 105 questions covering the major OS areas.
Which OS topics are most important?
Give special attention to CPU scheduling, process management, synchronization, semaphores, deadlocks, paging, page replacement, virtual memory, fragmentation and disk scheduling.
Is CPU scheduling important for DSSSB TGT?
Yes. Learn FCFS, SJF, SRTF, Priority and Round Robin, including waiting-time and turnaround-time calculations.
What is Belady's anomaly?
Belady's anomaly is the situation in which increasing the number of available page frames can increase the number of page faults. It is classically associated with FIFO page replacement.
Are the questions in this test exact previous-year questions?
This is a PYQ-oriented practice test. Some questions test concepts reported in previous papers, while many are original practice questions designed around recurring DSSSB-level concepts.
