Selected Learning Experiences
Introduction (7 minutes)
- Pose the key inquiry question to stimulate thinking
- Show two diagrams:
- Diagram 1: All computers connected in a circle (ring)
- Diagram 2: All computers connected to central point (star)
- Ask: “Which setup do you think is better? Why?”
- Brief discussion on how arrangement affects performance
- Present analogy: “Network topology is like city planning”
- Roads arranged differently affect traffic flow
- Same with data in networks
- Show real-world example: School computer lab arrangement
- Introduce lesson focus: Understanding network arrangement terminology
