Detailed explanation-1: -In star topology, the central site plays an important role; if it fails, all the connections will go down. Performance of the central hub dictates the performance of the connection. For a star topology, it may happen that two nodes might be closed to each other; however, they will have to communicate via central node.
Detailed explanation-2: -3 The primary disadvantage of the star topology is the hub is a single point of failure: If the hub were to fall short the whole network would fail as a result of the hub being connected to every computer on the network. There will be communication break down between the computers when the hub fails.
Detailed explanation-3: -Disconnecting a particular node in a star network will not disrupt service on the rest of the network, and the concentrator can easily locate a malfunctioning network node. If the concentrator fails, the entire network will be disabled. Some examples of star network include Ethernet switches and hubs.
Detailed explanation-4: -High cost: Central device Dependency: High maintenance: Prone to damage: Low data transfer rates in the wireless system: Immobile network system:
