Which topology gives the best reliability with the least wiring, as described in the text?

Bus, because it has one cable
Ring, because a single break does not stop the network
Star, because gateways give redundancy
Point-to-point, because it has the fewest nodes

Show answer

Correct answer: Ring, because a single break does not stop the network

Each node has two connection points. The network must be interrupted to add or remove a node.
