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

Star TopologyPros:
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

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

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