Which type of network topology features a central hub connected to all nodes?

Star topology is characterized by a central hub or switch that serves as the connection point for all nodes in the network. Each node, such as a computer or device, is individually connected to this central hub using separate communication cables.

This design offers several advantages. For one, if a single connection fails, it does not affect the rest of the network, allowing for greater reliability and easier troubleshooting. Additionally, adding or removing devices is simpler, as it only involves connecting or disconnecting a cable from the central hub without disrupting the entire network.

In contrast, mesh topology has every node interconnected, creating multiple paths for data to travel. Bus topology uses a single backbone cable where all nodes connect to, which can lead to network failure if the main cable is damaged. Ring topology connects nodes in a circular manner, where each device is connected to two others, forming a closed loop. In both bus and ring topologies, if one connection fails, it can impact the entire network more significantly than in a star topology.
