1. BEHAVIOURAL OBJECTIVES

By the end of the lesson, students should be able to:

1. Define a computer network.
2. State at least four reasons computers are connected in networks.
3. Explain LAN, MAN and WAN with relevant examples.
4. Identify common network devices and state their functions.
5. State the advantages and disadvantages of computer networks.
6. Differentiate between a computer network and the Internet.

2. INSTRUCTIONAL / TEACHING AIDS

• Desktop computer or laptop.
• Router and Ethernet cable, where available.
• Pictures of a network switch, modem and network interface card.
• Chart showing LAN, MAN and WAN.
• Whiteboard and markers.

3. PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR

Students have learnt about basic computer communication, including wired and wireless communication and the Internet.

Teacher's entry questions:

1. What is computer communication?
2. How can two computers exchange files?
3. Have you seen computers connected to the same printer or router?

4. PRESENTATION STEPS

STEP / TIME	TEACHER'S ACTIVITY	STUDENTS' ACTIVITY
Step 1: Introduction 10 minutes	Reviews computer communication and asks students how computers in a laboratory might share files and printers. Introduces the meaning of a computer network.	Answer questions and give examples of connected digital devices.
Step 2: Meaning and Reasons for Networking 15 minutes	Defines a computer network and explains resource sharing, communication, collaboration, and shared Internet access.	Take notes and mention reasons computers are connected in networks.
Step 3: Types of Networks 15 minutes	Explains LAN, MAN and WAN using examples from a school, a city and different countries.	Identify each network type and match it with the appropriate coverage area.
Step 4: Network Devices 15 minutes	Displays or describes a router, switch, modem, network interface card, network cable and wireless access point. Explains their functions.	Observe the devices or pictures and state the function of each device.
Step 5: Advantages and Disadvantages 15 minutes	Discusses resource sharing, faster communication, cost savings, security risks, equipment failure and maintenance. Explains the difference between a network and the Internet.	List advantages and disadvantages and explain the difference between a local network and the Internet.
Step 6: Evaluation and Conclusion 10 minutes	Asks oral questions, corrects misconceptions, summarises the lesson and gives an assignment.	Answer questions, summarise key points and copy the assignment.

Total Duration: 80 Minutes
