Subject: Information Communication Technology ICT
Lesson Topic: Know and understand common network devices including network interface cards (NIC), hubs, bridges, switches
Learning Objective/s:
  • Describe the function and OSI layer of NICs, hubs, bridges, and switches.
  • Compare the collision domains and traffic handling of each device.
  • Identify the most appropriate device for a given network scenario.
  • Explain how MAC address tables enable switches to forward frames efficiently.
  • Demonstrate basic configuration concepts using a network simulation tool.
Materials Needed:
  • Projector and screen
  • Student worksheet with comparison table
  • Laptops with network simulation software (e.g., Cisco Packet Tracer)
  • Printed handouts of OSI layers and device diagrams
  • Physical network cable samples for demonstration
  • Whiteboard and markers
 Introduction:
Begin with a quick question: “What lets your computer talk to the internet?” Students recall that a NIC is required. Review that they already know the basics of the OSI model. Explain that by the end of the lesson they will be able to differentiate common network devices and choose the right one for a given situation.
Lesson Structure:
  1. Do‑now (5’) – List devices seen at home or school and their perceived purpose.
  2. Mini‑lecture (10’) – Overview of NICs, hubs, bridges, and switches with projected diagrams.
  3. Guided comparison activity (12’) – Pairs complete a worksheet comparing OSI layer, collision domain, and typical use.
  4. Hands‑on simulation (15’) – Using Packet Tracer, students build a small network containing each device and observe traffic flow.
  5. Think‑pair‑share (5’) – Discuss which device is most efficient for a given scenario and why.
  6. Formative check (3’) – Quick Kahoot quiz on key concepts.
  7. Recap & exit ticket (5’) – Students write a brief scenario and select the appropriate network device.
Conclusion:
Recap that NICs provide endpoint connectivity, hubs broadcast to all ports, bridges segment traffic, and switches intelligently forward frames using MAC tables. Collect exit tickets where each student records a scenario and the device they would choose. For homework, ask learners to research a real‑world switch feature (e.g., VLAN) and prepare a short explanation to share next class.
