A central switch connects all devices in a primary school classroom. Identify this topology.
Star Topology
Every device has a dedicated cable to the central switch.
Exam 2: The Robustness Trap
Explain one benefit of a Mesh topology. [2 Marks]
⚠️ The Trap
"A mesh is much faster because data can take shortcuts."
✅ The Mark Scheme
1. It is robust with no single point of failure. 2. Data can be automatically rerouted if a node fails.
Exam 3: Failure Audit
What happens if the central device fails in a Star topology?
The whole network goes down.
All communication between nodes is lost because the hub/switch is the single path.
Exam 4: The Airport Blueprint
An airport office has five computers and two printers all connected to one central switch. This is a Star Topology — every device has its own dedicated cable to the switch.
━━ Solid = Computer cable╌╌ Dashed = Printer cableAll cables connect to the central Switch only.
