RING topology all computers are connected in loop. A ring topology is a network topology in which every node connects to exactly two other devices, forming a single continuous pathway for ways through each device - a ring. Data transfer from device to device, with each node along the way handling every message. Because a ring topology gives only one pathway between any two ways, ring networks can be disrupted by the end of a single link. A node end or cable break might isolate each node attached to the ring.
