Operating System Practical Viva Questions in IGNOU
Preparing for the Operating System Practical Viva in IGNOU is a crucial step for BCA and MCA students who want to do well in their practical exams. The viva tests not just your memory but also your understanding, logical thinking, and ability to explain your lab work. This detailed guide on Academicvox.com is specifically for IGNOU students and follows the official syllabus, lab structure, and evaluation pattern set by the university.
The Operating System practical generally corresponds to courses like BCSL-063 (Operating System Concepts and Networking Management Lab) for BCA students and similar lab courses for MCA students. You can always check the latest syllabus and practical structure on the official IGNOU website: https://www.ignou.ac.in/
Understanding the IGNOU Operating System Practical Viva
The practical viva takes place alongside the lab exam at your assigned study center. During the viva, the examiner asks questions about the experiments you performed, the commands you used, and the theories behind them. The goal is to see if you genuinely understand how an operating system works rather than simply recalling commands.
IGNOU values practical knowledge. This is reflected in the viva format. According to the official program guide on the IGNOU website, practical courses significantly impact your final results, making preparation for the viva very important.

Importance of Operating System Practical Viva for IGNOU Students
Many students overlook the viva and concentrate solely on completing the practical file or lab tasks. However, the viva often determines the difference between an average score and a high one. Examiners frequently ask straightforward but concept-based questions. If you know your fundamentals, you can answer confidently without needing to memorize long definitions.
The viva also demonstrates your seriousness as a student. Those who can explain why a command is used, how a process is created, or what happens in memory during execution are more likely to make a positive impression.
Official IGNOU Syllabus Reference for OS Practical
Before preparing viva questions, it’s essential to study in line with the official IGNOU syllabus. IGNOU offers detailed lab manuals and course material through eGyankosh, its digital repository. The official lab material for Operating System practical can be accessed here: https://egyankosh.ac.in/
Always study according to the experiments listed in the lab manual because viva questions are almost always based on those exercises.
Basic Operating System Concepts Viva Questions
One of the initial areas examiners focus on is basic operating system concepts. These questions help them assess whether you understand what an operating system is and its necessity.
Common viva questions include inquiries about what an operating system is, its main goals, and its role within a computer system. You should explain that an operating system serves as an interface between the user and the hardware, managing resources like CPU, memory, and storage effectively.
You may also encounter questions about different operating system types such as batch operating systems, time-sharing operating systems, real-time operating systems, and distributed operating systems, along with real-world examples.
Process Management Viva Questions
Process management is a key topic in operating systems and is frequently addressed in IGNOU viva exams. Examiners often ask what a process is and how it differs from a program. You should clarify that a program is a set of instructions, while a process is an active instance of that program during execution.
Other frequently asked questions cover process states, the process control block, and context switching. You should understand and explain states like new, ready, running, waiting, and terminated. Context switching involves saving the state of a running process and loading the state of another one so that the CPU can switch tasks smoothly.
CPU Scheduling Viva Questions
CPU scheduling algorithms are another commonly explored area for viva questions. You should know the purpose of CPU scheduling and its necessity in a multiprogramming environment. Examiners might ask you to explain algorithms like First Come First Serve, Shortest Job First, Priority Scheduling, and Round Robin.
Prepare to discuss the advantages and disadvantages of each algorithm, along with average waiting time, turnaround time, and starvation. Using practical examples makes your answers more relatable.
Memory Management Viva Questions
Questions about memory management test your understanding of how the operating system allocates and manages memory. You may need to explain what memory management is and its significance. Common topics include paging, segmentation, virtual memory, and demand paging.
Understand the difference between paging and segmentation, and be ready to explain how virtual memory allows a system to run large programs even with limited physical memory.
Deadlock and Synchronization Viva Questions
Deadlock is a conceptual topic often featured in the IGNOU OS practical viva. Common questions cover what deadlock is, the conditions necessary for it to occur, and how it can be prevented or avoided.
Remember the four necessary conditions for deadlock: mutual exclusion, hold and wait, no preemption, and circular wait. Synchronization-related questions may address semaphores, critical section problems, and race conditions.
File System Viva Questions
File system concepts are closely related to practical OS usage. Examiners might ask about files, directories, file permissions, and file allocation methods. You should be comfortable explaining what a file system is and how the operating system organizes data on storage devices.
In Linux-based practicals, expect common questions about file permissions, ownership, and directory structure.
Linux and UNIX Commands Viva Questions
IGNOU Operating System practicals often involve working with Linux or UNIX commands. During the viva, you may need to explain commands used in the lab. Common commands include ls, pwd, cd, mkdir, rmdir, cp, mv, rm, chmod, and ps.
Be prepared to explain what each command does and, in some cases, discuss commonly used options. For instance, chmod changes file permissions, and you should understand both symbolic and numeric modes.
Shell Scripting Viva Questions
Shell scripting is vital in OS practicals. Examiners may ask what a shell is, why shell scripts are used, and how variables and conditional statements function in shell scripting.
You may need to explain a script you wrote in your practical file. It’s essential to understand the logic behind your script rather than just memorizing it.
Networking Basics in OS Practical Viva
Some IGNOU OS practical courses also cover basic networking concepts. Viva questions may ask about what a network is, types of networks like LAN, MAN, and WAN, and basic networking commands.
Be aware of the operating system’s role in networking, such as managing network resources and enabling communication between systems.
Practical File and Viva Connection
Your practical file is critical for the viva. Examiners often ask questions based on the experiments recorded in your file. If you copied the file without understanding its content, it will be challenging to answer viva questions.
Ensure your practical file is complete, well-organized, and signed by your lab instructor. Always review each experiment before exam day.
How IGNOU Evaluates OS Practical Viva
IGNOU uses a structured evaluation system for practical courses. Marks are given for practical performance, the practical file, and the viva. You can find the exact distribution of marks in the official assignment and course details provided by IGNOU.

Common Mistakes Students Make in Viva
Many students lose marks in the viva due to nervousness, unclear concepts, or lack of practice. Giving one-word answers, using incorrect terms, or confusing concepts like process and thread are typical mistakes.
Another major error is not revising basic definitions. Examiners usually start with simple questions to help you relax, but incorrect answers at this stage can dent your confidence.
Tips to Prepare Effectively for OS Practical Viva
Start your preparation by thoroughly reading the official IGNOU study materials and lab manual. Practice commands regularly on a Linux system to build confidence.
Try explaining concepts aloud as if you were answering an examiner. This enhances clarity and reduces hesitation during the actual viva. Reviewing previous year questions and discussing them with classmates can also help.
Role of Official IGNOU Resources in Preparation
Always rely on official IGNOU resources for preparation. Study materials from eGyankosh and details on the IGNOU website are accurate and aligned with the exam pattern.
