What is a data collision?

A fault in the logical topology such that multiple nodes are able to transmit at the same time

Data traffic can be automatically diverted around faults.

Each node contains redundant components that take over should the primary component fail.

Two or more physical rings are installed.

Cables are able to repair themselves when broken.
