Which topology allows for the addition and removal of devices without impacting the entire network?

The star topology is notable for its ability to allow the addition and removal of devices without significantly affecting the overall network. In this configuration, all devices are connected to a central hub or switch. When a device needs to be added or removed, it can be done with minimal disruption, as the central device manages the connections.

This design isolates each device in the network, meaning that if one device is disconnected or fails, the other devices remain operational. This characteristic is particularly useful in environments where devices are frequently added or changed, such as in offices or educational institutions.

The star topology's reliance on a central connecting device also simplifies troubleshooting, as issues can be isolated to specific connections between the devices and the hub. This makes maintenance easier and helps to ensure that the network remains stable and operational even when changes are made.
