Data travels in one direction (or sometimes both, in a dual ring) from node to node until it reaches its destination.

Explanation

Coaxial cables typically support data transmission speeds between 10 Mbps to 200 Mbps, used in cable TV and internet.

They are shielded and suitable for medium-speed data over longer distances than twisted-pair cables.
