SHS2 Computing · Semester 1 Week 16: Data Communication and Network Systems

Lesson notes

Learning Objectives

Indicator: 2.1.3.LI.3 - Discuss and compare at least three network topologies.

By the end of the lesson, learners can:

Define network topology and identify at least three common types (bus, star, ring) with their key features.
Draw and label diagrams of bus, star, and ring topologies showing how devices are connected.
Compare bus, star, and ring topologies across at least three criteria (cost, fault tolerance, performance) using a comparison table.
Discuss the advantages and disadvantages of each topology in a class discussion, giving reasons for their views.
Select an appropriate topology for a given real-life scenario and justify their choice with at least two valid reasons.

Exemplars (from the NaCCA curriculum)

Talk for Learning Approach: Contrasting Network Topologies: Use question-andanswer sessions to facilitate discussions among learners on the characteristics of three network topologies. Invite individual learners to demonstrate how to connect devices like hubs, routers, bridges, and switches, while others provide comments and feedback.
