JHS1 Computing · Term 3 Week 1: Computer Networks

Lesson notes

Learning Objectives

Indicator: B7.3.1.1.1 - Draw diagrams to illustrate features of the network topologies (Bus, Star, Ring, Mesh)

By the end of the lesson, learners can:

Define a network topology and name the four main types: Bus, Star, Ring, and Mesh.
Describe the key features and physical layout of each of the four network topologies.
Identify the hardware components (server, client, hub, switch, cable) used in each topology.
Draw and label clear diagrams of Bus, Star, Ring, and Mesh topologies.
Compare the advantages and disadvantages of at least two topologies when choosing a network for a given situation.
