A major advantage of a ring topology is that signal degeneration is low because each
work station is responsible for regenerating or boosting the signal. With the other
topologies, as the signal travels the wire, it gets weaker and weaker as a result of outside
interference: eventually, it becomes unreadable if the destination system is too far
away. Because each work station in a ring topology regenerates the signal, the signal is
stronger when it reaches its destination and seldom needs to be retransmitted.
