![]() ![]() In the last few years, star topologies have become more popular because their price has gone down and they are more flexible.For example, the original twisted pair Ethernet using repeater hubs was a logical bus topology carried on a physical star topology.The star topology reduces the impact of a line failure by connecting all of the systems to a central node.The hub on the other hand, while maintaining a logical ring, allows a star topology on the cable level.While IBM's token ring is a logical ring topology, it is physically set up in star topology.Star topology systems can be converted to multipoint systems by installing new conductors between old existing ones.A twisted pair Ethernet is a logical bus topology in a physical star topology layout.10BASE-T, 100BASE-T, and 1000BASE-T installations running on twisted pair cable use a star topology.CAT6 ethernet is always wired in what is called a star topology. ![]()
