Star Topology

A star topology is a topology for a Local Area Network (LAN) in which all nodes are individually connected to a central connection point, like a hub or a switch. A star takes more cable than e.g. a bus, but the benefit is that if a cable fails, only one node will be brought down.

Main Advantage: In a star network, one malfunctioning node doesn’t affect the rest of the network.
Main Disadvantage: If the central computer fails, the entire network becomes unusable
