2. Explain why computers and digital devices are connected in networks.
3. State at least four reasons for using computer networks.
4. Define LAN, MAN and WAN.
5. Differentiate between LAN, MAN and WAN based on geographical coverage.
6. Give examples of situations where LAN, MAN and WAN can be used.

INSTRUCTIONAL / TEACHING AIDS

• Computers or laptops
• Network diagrams and charts
• Network cables
• Router
• Projector
• Whiteboard and markers
• Pictures showing LAN, MAN and WAN

PREVIOUS KNOWLEDGE / ENTRY BEHAVIOUR

Students have learned about computers, hardware and software in JSS 1. They have also encountered the idea of connecting digital devices to the Internet and may have seen computers sharing information through a school or home network.

PRESENTATION STEPS

Step	Teacher's Activity	Students' Activity
1. Introduction	The teacher asks students whether they have seen two or more computers connected together and asks what they think happens when devices are connected.	Students share their experiences and suggest reasons why devices may be connected.
2. Meaning of Network	The teacher explains that a computer network is a group of computers and other digital devices connected together so that they can communicate and share resources and information.	Students listen, take notes and explain the meaning in their own words.
3. Need for Networks	The teacher discusses reasons for networking, including sharing files, printers, Internet connections and other resources, as well as communication and collaboration.	Students identify examples of resources and information that can be shared over a network.
4. LAN	The teacher defines Local Area Network (LAN) and explains that it normally covers a small geographical area such as a classroom, computer laboratory, office or school building.	Students give examples of places where a LAN may be used.
5. MAN	The teacher explains Metropolitan Area Network (MAN) as a network that can connect networks across a larger area such as parts of a city or metropolitan area.	Students compare MAN with LAN and discuss possible examples.
6. WAN	The teacher explains Wide Area Network (WAN) as a network covering a large geographical area and gives examples such as networks connecting locations in different cities or countries.	Students explain how WAN differs from LAN and MAN.
7. Comparison	The teacher presents a comparison of LAN, MAN and WAN based mainly on geographical coverage and typical use.	Students complete a simple comparison table in their notebooks.
8. Conclusion	The teacher reviews the meaning of a network, reasons for networking, and the differences among LAN, MAN and WAN.	Students answer oral review questions and ask questions where necessary.

EVALUATION QUESTIONS

1. What is a computer network?
2. State four reasons why computers are connected in networks.
3. What does LAN mean?
4. What does MAN mean?
5. What does WAN mean?
6. State one major difference between LAN, MAN and WAN.
7. Give one example of where a LAN can be used.

ASSIGNMENT

Draw a simple diagram showing three computers connected in a network. Under the diagram, write two benefits of connecting the computers together.

TEACHER'S REFLECTION

The teacher should note students' ability to explain the purpose of computer networks and distinguish LAN, MAN and WAN. Any difficulty in understanding geographical coverage should be reinforced with simple diagrams and familiar examples.
