Which network topology forms a closed loop?

In a ring topology, each device on the network is connected to two other devices, forming a closed loop. Data travels in one direction around the ring, from one device to the next, until it reaches its intended destination. This structure allows for efficient data transmission within the network, as the signal passes through each device sequentially.

Unlike other topologies, a ring configuration can simplify the process of managing data traffic since each device has a defined role in the order of transmission. This can help minimize collisions compared to bus topologies. The closed-loop nature of a ring topology also allows specific network characteristics, such as predictable latency and ease of fault diagnosis, which can be advantageous in certain scenarios.
