- 1TopologiesMost networks are connected together in one of three ways called a topology. Topology just means a way of laying
things out. - 2Star TopologiesEach computer is connected to a central device which coordinates all the traffic.
This works well because if one cable fails the other computers are not affected. It is easy to add new
computers to the network. However if the central device fails then the whole network will stop working. - 3Bus TopologyEach computer is connected to a single cable and data can travel in both directions along this
cable - like a bus route. This type of network is easy to set up and it’s very simple to add more computers. However if the central cable fails then so will the network. - 4Ring TopologyEach computer is connected to the ones either side of it. Data is sent in one direction around the ring until it finds the computer it was sent to. This is good because there is no reliance on a central server to coordinate the traffic but if any of the nodes breaks then the whole network is disrupted. It can also be quite
difficult to add new computers to a Ring network.
