less expensive

less cables

robust

easier to detect faults

easier installation

hub dependent

uses more resources

more regural maintenance intervals

the pcs communicates trough an hub

easy installation

fewer cable used

faults are harder to detect

backbone dependent

is not scalable

nodes are limited

backbone cables and drop lines

it's scalable and the best topology can be chosen

choice based on needs

design is complex and maintence is very high

difficult to install

faults are difficult to detect

combination of topologies
