SHS3 Ict · Semester 2 Week 10: Guided and Unguided Network Systems

Lesson notes

Learning Objectives

Indicator: 3.2.1.LI.1 - Describe Commonly used Devices (e.g., broadband, modems, wireless access points, routers, network cards, hubs and switches).

By the end of the lesson, learners can:

Define each of the seven network devices (broadband, modem, wireless access point, router, network card, hub, and switch) in their own words.
Explain the primary function and purpose of each device in a network communication system.
Compare and contrast the characteristics, advantages, and limitations of at least three pairs of network devices (e.g., hub vs switch, modem vs router, wireless access point vs router).
Categorise the devices according to whether they are primarily used in wired networks, wireless networks, or both.
Justify the choice of appropriate network device(s) for a given real-life connectivity scenario, explaining the reasoning behind their selection.
