Computer Network Topology – Solved Scenario Questions
In this post we analyze a real computer network scenario for an international company and answer key questions related to network topology, connection devices, network types, and calculation of ports and links. This is great practice for exams in Computer Science & Networking.
Scenario
Suppose an international company AECOM has two computer network sections named “Admin” and “Employees”.
The Admin section has 21 computers which are directly connected with each other for efficient communication.
The Employees section has 35 computers connected through an intelligent central device, and a video conference link has been established for an online event abroad.
Questions and Answers
1. Identify the type of network topology used in the Admin section.
Since every computer in the Admin section is directly connected to every other computer with no central device or hub, it forms a Mesh Topology. In a mesh structure, each device has a dedicated point-to-point link to every other device. :contentReference[oaicite:0]{index=0}
2. Name the intelligent device used in the Employees section and its topology.
The intelligent device used for connecting computers in the Employees section is a Switch, and the topology formed is Star Topology, where all nodes connect to a central device. :contentReference[oaicite:1]{index=1}
3. Identify the network type required to connect to the video conference.
To connect the local network with a distant conference computer, a Wide Area Network (WAN) is required because it spans a large geographic area and connects multiple smaller networks. :contentReference[oaicite:2]{index=2}
4. Total number of ports required on each computer in the Admin section?
In a full mesh network with N devices, each device must be able to connect to every other device. The number of ports required on each computer is:
N − 1 = 21 − 1 = 20
So each computer needs 20 ports to connect directly to the 20 other systems. :contentReference[oaicite:3]{index=3}
5. Total number of links required in the Admin section?
In mesh topology, total links are calculated as:
(N × (N − 1)) / 2 = (21 × 20) / 2 = 210
So the Admin section needs 210 physical links for full connectivity. :contentReference[oaicite:4]{index=4}
Summary
- Admin Topology: Mesh
- Central Device (Employees): Switch
- Employees Section Topology: Star
- Network Type for Conference: WAN
- Ports per Computer (Admin): 20
- Total Links (Admin): 210

Frequently Asked Questions (FAQs)
What is Mesh Topology?
Mesh topology is a network design where every device has a direct link to every other device, offering high reliability but requiring many connections.
Why is a switch used in star topology?
A switch serves as a smart central hub that manages data traffic efficiently by sending data only to the intended recipient device.
What defines a WAN?
A Wide Area Network (WAN) connects computers and networks across large geographic distances, often through the internet.
