What are the logical characteristics of star topology?

Star topology is characterized by a central hub or switch to which all nodes (devices) are directly connected, creating a hub-and-spoke configuration. This setup allows for easy addition or removal of devices without disrupting the network, as each node is independently connected. If one connection fails, it does not affect the entire network, enhancing reliability. However, the central hub represents a single point of failure, meaning that if it fails, the entire network becomes inoperative.
