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.
1. logical topology 2. Physical topology 3. star toplogy
logical channel
token ring uses a physical star and a logical ring ,while FDDI uses a physical star/ring and a logical ring.

It is wired internet, it uses just a basic cable to give computers internet connections if they have what is called an Ethernet port. It is also generally faster than Wi-Fi or 3G which are a couple wireless forms of internet.
A star topology.
Star topology
Bus topology as many nodes are connected to single link
Two-factor authentication uses something a user has in conjunction with something a user knows.
Token ring uses star topology . The data token is being passed from one computer to other allowing all the computer to have network access and avoids data collision.
Bus
