In the Star Topology, collection of computers can connect in the centralized communication hardware devices are called Ethernet Hub and Network Switch. Star Topology is a simplest and expensive method to connect multiple computers in the shared hardware device and Network Maintain Cost is low when adding additional Computer and Hardware in the Network Environment. Star Topology is suitable to interconnect many computer and hardware devices in the Network Environment. Ethernet Hub and Network Switch is help to avoid Network Collusion and reduce the Server Computer workload. The data transmission is happened through individual Network Cable Wire. The Network should not shutdown, when, disconnect Network Cable Line expect the Ethernet Hub and Network Switch Problem. Star Topology is a common method in the Computer Network Environment.
