Bus Topology
It's used for Star topology.
Each device is a repeater

SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
How do hosts on a physical ring topology communication
Topology is the actual layout of the network, for instance, where the routers and other devices are located. That would be the networks topology.

A ring topology connects neighboring nodes until they form a ring. * signals than travels in one direction around the ring; each device on the network acts as a repeater to send the signal to the next device.
no difference,,,tree and hybrid are same.
In a ring topology, devices are connected in a circular fashion, and the primary device used to connect these devices is a network switch or a repeater. Each device is linked to exactly two others, forming a closed loop for data transmission. Data travels in one direction around the ring, and if one device fails, it can disrupt the entire network unless a dual-ring configuration is implemented for redundancy.
