9. Bus Topology Pros: Easy to install Not expensive Not much cable required Cons: Hard to troubleshoot, change, move A single cable failure – bus itself

10. Star Topology Pros: Easy to add new stations A single cable failure is not a big deal Easy to troubleshoot Cons: Larger number of cables necessary A single point failure

11. Physical Net. Topology Ring – hard to add new, single cable failure Mesh – most fault tolerance Point-to-PointPoint-to-Multipoint Hybrid Topology – Internet as an example

12. Choose Right Topology Cost Ease of installation Ease of maintenance Fault-tolerance requirement Examples: simple home network – wireless access point simple home network – wireless access point A fast growing company – wired star Godzilla-strength fault-tolerance -- hybrid
