Understanding Network Topologies: Quiz & Insights

Are you ready to test your networking knowledge? Let’s explore some key concepts about network topologies and computer communication.

1️⃣ Bus Topology and Multipoint Connections

Question: Does a bus topology require a multipoint connection? Why or why not?

💡 Tip for readers: Think about how multiple devices share a single cable.

2️⃣ Keyboard and Computer Communication

Question: Is the communication between a computer and a keyboard half-duplex, full-duplex, or simplex? Explain your answer.

💡 Hint: Consider which direction the data flows and whether it can be simultaneous.

3️⃣ Cabling in Different Topologies

Question: In a network of 25 PCs, which topology—bus, star, mesh, or ring—requires the most cabling? Why?

💡 Hint: Some topologies need every device to connect to every other device.

4️⃣ Mesh Topology Cable Calculation

Question: How do you calculate the number of cables required in a full mesh topology? For example, how many cables would 25 PCs need?

💡 Hint: Use the formula:

Cables = n(n-1)/2

5️⃣ Comparison of Topologies

Question: How does cabling scale as the number of PCs increases in bus, star, mesh, and ring topologies?

💡 Tip: Consider which topologies grow linearly vs. exponentially.

6️⃣ Practical Implications

Question: What are the advantages and disadvantages of using a mesh topology despite its high cabling requirements?

💡 Think about: Reliability, cost, and maintenance.

From DSRC to 5G NR-V2X: The Road Ahead for Connected Vehicles

Modern vehicles are no longer just machines on wheels. Through Vehicle-to-Everything (V2X) communication , they are becoming active participants in intelligent transport systems, enabling safer driving, smoother traffic, and progress toward automation. DSRC: The First Step The earliest V2X technology was Dedicated Short-Range Communications (DSRC) , based on IEEE 802.11p. Operating in the 5.9 GHz band , it allowed onboard units (OBUs) in vehicles to exchange safety and infotainment data with roadside units (RSUs) . While DSRC was effective for short-range messaging, it faced limits in coverage, data rate, and quality of service (QoS) . These challenges motivated researchers to explore new solutions. D2D and the Cellular Shift A key breakthrough came with Device-to-Device (D2D) communication , where vehicles exchange information directly without always relying on infrastructure. This reduces latency, eases network congestion, and helps maintain reliability in crow...
