IGNOU Computer Network Practicals Explained
Introduction to Computer Network Practicals in IGNOU
Computer Network practicals are a vital part of IGNOU’s computer programs like BCA, MCA, PGDCA, and other IT courses. These practicals help students learn how computer networks function in real-world situations, going beyond just theory. For many students, Computer Networks can seem complicated, but IGNOU makes the practical part straightforward, syllabus-focused, and easy to understand.
Knowing the structure, expectations, and evaluation pattern of Computer Network practicals allows students to prepare effectively and perform well.

Objective of IGNOU Computer Network Practicals
The main goals of Computer Network practicals are:
- To learn basic networking concepts
- To recognize network components and devices
- To understand IP addressing and basic network configuration
- To perform simple networking commands and tasks
- To gain clarity on real-world networking scenarios
IGNOU does not expect students to have industry-level configuration skills, especially at the undergraduate level.
Overall Structure of IGNOU Computer Network Practicals
IGNOU Computer Network practical exams usually include:
- A practical task or experiment
- Questions related to the performed task
- Evaluation of the practical file or lab record
- Viva voce (oral examination)
Marks are distributed among performance, file work, and viva, so balanced preparation is necessary.
Types of Practical Questions Asked
Most Computer Network practical questions fall into these categories:
- Identification-based questions
- Configuration-based tasks (basic level)
- Command-based questions
- Conceptual explanation questions
- Viva questions from the practical file
All questions are strictly guided by the official lab manual.
Network Device Identification Questions
Students often need to identify and explain:
- Hub
- Switch
- Router
- Modem
- Network Interface Card (NIC)
- Cables and connectors
Common questions include:
- What is the function of this device?
- Where is it used?
- What is the difference between a hub and a switch?
These questions assess basic understanding rather than memorization.
IP Addressing and Networking Basics
IP addressing is an essential topic in Computer Network practicals.
You may be asked to:
- Explain the structure of an IP address
- Differentiate between IPv4 and IPv6
- Identify the network and host parts
- Explain subnet masks conceptually
Numerical subnetting problems are usually simple or skipped in first-level practicals.
Networking Commands Practicals
In some study centers, students may be asked to demonstrate or explain basic networking commands such as:
pingipconfigifconfigtracert
Examiners generally focus on:
- The purpose of the command
- A basic explanation of the output
- Practical uses
You do not need to memorize complex command options.
Network Topology Questions
Students should understand common network topologies like:
- Bus topology
- Star topology
- Ring topology
- Mesh topology
Practical questions may include:
- Drawing a topology diagram
- Explaining the advantages and disadvantages
- Identifying where a topology is used
Clear diagrams and simple explanations are enough.
OSI Model and TCP/IP Model Questions
Although theoretical, these models often come up during the viva.
Common questions include:
- What is the OSI model?
- How many layers are there?
- What is the purpose of each layer?
- What is the difference between the OSI and TCP/IP models?
You should explain functions, not detailed protocols.
Practical File Role in Computer Network Practicals
The practical file is crucial for evaluation. Examiners often ask questions taken directly from your file.
A typical Computer Network practical file includes:
- Cover page with student details
- Course code and title
- Index
- Experiments or practical tasks
- Diagrams and explanations
- Viva questions (if included)
Official student guidelines can be found at:

How to Write Computer Network Practical Experiments
Each experiment should be clearly written with:
- Aim of the experiment
- Required tools or components
- Brief theory
- Procedure
- Result
- Diagram (if applicable)
Don’t copy blindly. Understanding what you write improves viva performance.
Viva Voce Pattern in Computer Network Practicals
Viva voce is usually:
- Short
- Concept-based
- Related to your practical file
Common viva questions might include:
- What is a computer network?
- What is the difference between LAN, MAN, and WAN?
- What is an IP address?
- What is the role of a router?
- Explain any one experiment from your file.
Viva questions are generally easy and straightforward.
How IGNOU Examiners Evaluate Network Practicals
Examiners focus on:
- Conceptual clarity
- Ability to explain basics
- Completeness of the practical file
- Honest effort during the exam
Perfect answers are not required; basic understanding is more important.
Marks Distribution in Computer Network Practicals
Though it varies by course, marks are generally divided into:
- Performance on practical tasks
- Practical file evaluation
- Viva voce
Strong performance in one part can make up for difficulties in others.
Common Mistakes Students Make
Avoid these mistakes:
- Memorizing answers without understanding
- Neglecting diagrams and the neatness of the practical file
- Giving one-word answers during viva
- Panicking when asked questions
- Skipping basic definitions
These errors can cost easy marks.
How to Prepare for Computer Network Practicals
Effective preparation should involve:
- Reading the lab manual thoroughly
- Learning about device functions
- Practicing diagrams
- Reviewing basic networking terms
- Preparing brief viva answers
Always use official IGNOU material.
Importance of Study Centre in Practicals
IGNOU practical exams take place at designated study centers.
Study centers:
- Conduct practical exams
- Verify attendance
- Send marks to IGNOU headquarters
Study centre details are available at:

Attendance Requirements for Network Practicals
Some courses require:
- Mandatory lab attendance
- Completion of internal practical sessions
Missing attendance may make you ineligible for practical exams in some cases.
What Happens If You Miss a Practical
If you miss your Computer Network practical:
- You might need to retake it in the next session
- You will not receive marks without attendance
Re-attempt rules depend on course guidelines from IGNOU.
