Lesson Plan

• Describe the characteristics and typical uses of LAN, WAN, VPN, and mobile networks.
• Compare the advantages and limitations of each network type.
• Evaluate which network type best fits a given scenario based on coverage, speed, security, and cost.

• Projector or interactive whiteboard
• Slide deck with network diagrams
• Handout summarising network types
• Whiteboard and markers
• Laptop with internet access for demo
• Sample VPN client software (e.g., OpenVPN)

Begin with a quick poll: “Which network are you using right now?” Discuss how everyday devices rely on different networks, review prior knowledge of basic networking concepts, and state that by the end of the lesson students will be able to identify and justify the appropriate network type for various situations.

1. Do‑now (5') – Students list devices they use and guess the network type.
2. Mini‑lecture (15') – Present definitions, coverage, media, and speeds for LAN, WAN, VPN, and mobile networks using slides.
3. Comparative table activity (10') – In pairs fill a provided table comparing advantages and disadvantages of each type.
4. Demonstration (10') – Show a simple VPN connection and a mobile hotspot on the classroom network.
5. Scenario analysis (15') – Groups receive case studies and decide which network type is optimal, justifying their choices.
6. Check for understanding (5') – Quick quiz (Kahoot/exit ticket) with three questions.

Recap the key differences in scope, speed, security, and cost across the four network types. Students write one takeaway on a sticky note as an exit ticket. For homework, research a real‑world example of each network type and prepare a brief summary.
