What is a key characteristic of a star topology in networking?

In a star topology, all network devices are connected to a central hub or switch. This central node serves as the focal point for communication within the network. Each device has a dedicated connection to the hub or switch, which helps in managing and routing data efficiently. The primary advantages of star topology include ease of installation and maintenance, as well as isolation of network issues. If a device fails, it does not affect the rest of the network, and only the connection between that device and the central hub is disrupted. However, if the central hub or switch fails, the entire network is affected because all communication passes through this central point.
