The star topology is constructed from a central device, either a switch, router, or hub, which every other node in the network connects to. In this design, each distinct cable only connects two physical devices, with one end hooking up to a node on the network and the other hooking up the central device. If one node wants to transmit data to another node, it must send its transmission to the central device, which will then act as a relay station and pass along the transmission to the destination node.
