A network topology in which each workstation is connected in series to the adjacent workstation. A transmitted message is sent from the point of origin around the ring through each workstation until it reaches its destination. Ring networks—such as Apple's LocalTalk or IBM's Token Ring—are not useful for large networks, and there is usually a limit to the number of devices and nodes that can be connected. Additionally, the serial arrangement means that if one node fails (i.e., one workstation computer crashes), any devices or workstations beyond that point cannot be accessed.
