Which topology listed below permits network extension with a minimal amount of interruption for the existing network users?

Each network device has a private cable to create point-to-point accessibility to a centralized device on a star network, such as a hub or a switch . With such a configuration, a new device is able to be added to the network by using its separate cable to connect the new device to the hub or switch through. This process does not discontinue the users who are currently on the network.
