A star topology relies on which central device to interconnect all end nodes?
a.A repeater between each pair of nodes
b.A central switch or hub
c.A shared coaxial bus
d.A ring of daisy-chained cables
Explanation
In a star topology every node connects to a central switch or hub, which forwards traffic between them. A failure of one cable affects only that node, improving fault isolation. Bus and ring topologies use shared media that create single points of failure.
