The computer network topology shaped like a ring is known as the ring topology. In this configuration, each device is connected to two other devices, forming a circular pathway for data signals. Data travels in one direction around the ring, which can reduce data collisions compared to other topologies like star or bus. However, if one device fails, it can disrupt the entire network. Ring topology is often used in local area networks (LANs) and can be effective in small to medium-sized setups where performance is a priority.
