The topology of the “ring”
In a network with a ring topology all the nodes are connected by links in unbroken ring (not necessarily a circle) at which data is transmitted. The output of a PC connected to the input of another PC. Having started the movement from one point, the data in the end, get on top of it. The data in the ring always move in the same direction.
Host workstation detects and receives only addressed her message. In a network with physical ring topology type used marker access, which gives the station the right to use the ring in order. Logical topology of the network – the logical ring. This network is very easy to create and customize. The main weaknesses of networks ring topology is that the damage to the lines of communication in one place or PC failure causes the entire network. Typically, pure topology of the “ring” is not used because of its unreliability, so in practice, apply various modifications ring topology.
