Every workstation is indirectly connected to every other through the central computer. In some star networks, the central computer can also operate as a workstation. The star network topology works well when workstations are at scattered points. It is easy to add or remove workstations. If the workstations are reasonably close to the vertices of a convex polygon and the system requirements are modest, the ring network topology may serve the intended purpose at lower cost than the star network topology. If the workstations lie nearly along a straight line, the bus network topology may be best. In a star network, a cable failure will isolate the workstation that it links to the central computer, but only that workstation will be isolated. All the other workstations will continue to function normally, except that they will not be able to communicate with the isolated workstation. If any workstation goes down, none of the other workstations will be affected. But if the central computer goes down, the entire network will suffer degraded performance or complete failure. If redundancy is required, the mesh network topology may be preferable.
