Ring Topology

In the ring topology, each computer is connected directly to two other computers in the net­work. Data moves down a one-way path from one computer to another, as shown in Figure1 .7. The good news about laying out cable in a ring is that the cable design is simple. The bad news is that, as with bus topology, any break, such as adding or removing a computer, disrupts the entire network. Also, because you have to “break” the ring in order to add another station, it is very difficult to reconfigure without bringing down the whole network. For this reason, the physical ring topology is seldom used.
