Network Topology Identification

Unit 4 - Network Types & Topologies

Instructions

Identify network topologies and compare their characteristics. Main topologies: Star, Bus, Ring, Mesh

Question 1: Identify the Topology (4 marks)

Name each network topology shown:

Topology A:

Topology B:

Topology C:

Topology D:

Question 2: Advantages and Disadvantages (4 marks)

Complete the table with ONE advantage and ONE disadvantage for each topology:

Topology Advantage Disadvantage
Star
Bus
Ring
Mesh

Question 3: Scenario Selection (3 marks)

Which topology would be most suitable for each scenario? Explain why.

a) A small office with 10 computers and a central server:

b) A network where reliability is critical and cost is not a concern (e.g., military):

c) A temporary network setup at an event with minimal cabling:

Question 4: Network Types (3 marks)

Match each network type to its description:

A. PAN
B. LAN
C. WAN
Network spanning multiple cities or countries
Network within a single building or campus
Network for personal devices within arm's reach

Question 5: Short Answer (2 marks)

a) What happens in a star topology if the central hub/switch fails?

b) Why is a bus topology rarely used in modern networks?

Q1: A-Star, B-Bus, C-Ring, D-Mesh
Q2 Star: Adv: Easy to add devices, one failure doesn't affect others. Disadv: Hub failure brings down network
Q2 Bus: Adv: Simple, cheap, less cabling. Disadv: Cable break affects all, collisions, limited length
Q2 Ring: Adv: Equal access, no collisions. Disadv: One break affects all, difficult to add devices
Q2 Mesh: Adv: Very reliable, multiple paths. Disadv: Expensive, complex, lots of cabling
Q3a: Star - centralized management, easy to maintain and expand
Q3b: Mesh - maximum redundancy, if one link fails data can use alternative paths
Q3c: Bus - minimal cabling required, quick to set up
Q4: C-WAN (cities/countries), B-LAN (building/campus), A-PAN (personal/arm's reach)
Q5a: The entire network goes down as all devices connect through the hub
Q5b: Limited scalability, collision issues, single point of failure, slow compared to modern star networks
