The computers are connected with one cable to a ring-like network. The RING-topology is similar to the BUS-topology because it also has just one cable. There are only differences in the data transmission.
Data Transmission:
If one computer sends a message to another computer the transmitter sends the message with the destination address. Every computer checks the destination address with his own address. If it isn¡¦t the same the computer amplifies the computer signal and sends it to the next com-puter in the ring structure (in a BUS-topology the computer doesn¡¦t am-plifies the signal). If a computer amplifies a computer signal we speak from a active topology. Otherwise, for example the BUS-topology is a passive topology.
Advantage:
"³ it¡¦s very good for large networks
Disadvantage:
"³ if one computer has a failure the network breaks down
