In which of the following topology computers and devices are connected to a closed loop cable? 

In Ring Topology, computers and devices are connected to a closed loop cable. Here there are no terminating ends so if one system crashes the entire network goes down. Each computer functions as a repeater and charges the signal before sending it to the next station. In Ring topology, data is sent through the network by way of a token. If the token isn’t carrying any data, a computer waiting to send data seizes it, attaches the data and the electronic address to the token and sends it on. Once the token is received by the destination computer it strips the data and the token is sent on. This is why it’s named a token ring network.
