Topology

The geometric arrangement of a computer system. Common topologies include a bus (network topology in which nodes are connected to a single cable with terminators at each end), star (local area network designed in the shape of a star, where all end points are connected to one central switching device, or hub), and ring (network topology in which nodes are connected in a closed loop; no terminators are required because there are no unconnected ends). Star networks are easier to manage than ring topology..”
