Learning Objectives

Indicator: 1.2.1.LI.1

By the end of the lesson, learners can:

Classify network types into LAN, MAN, and WAN based on the geographical area they cover and give a Ghanaian example of each.
Define network topology and explain the arrangement of devices in a network.
Identify and describe the four main topologies: star, ring, bus, and mesh, including their advantages and disadvantages.
Draw a labelled diagram of each of the four topologies in their exercise books.
Justify the choice of a particular topology for a given real-life scenario, giving reasons based on cost, reliability, and ease of setup.

Exemplars (from the NaCCA curriculum)

● Engage in interactive learner-centred teaching and learning to explain different understanding network topologies, such as star, ring, bus, and mesh. ● Utilise multimedia presentations and video analysis, such as YouTube videos, to reasoning discuss the concepts and techniques of both wired and wireless networks. ● Ensure the strategies adopted do respond to inclusivity and equity, supporting diverse learners with visual impairment, dyslexia, dysgraphia, and other needs.
