(i) Give two advantages and two disadvantages of star topology
Answer
|
Advantages |
Disadvantages |
| 1. It is very reliable – if one connection or device fails then all the others will still be working, and hence the network stays stable. | 1. Central node dependency; i.e., If the central network device (hub/switch) fails, then none of the connected nodes can work without it |
| 2. Its setup is less expensive since each device/node only needs one I/O port which connects with the hub via a single link | 2. Hub requires more resources and regular maintenance because it’s the central system of the network. |
| 3. No disturbances to the established network when connecting or removing any device/s. | 3. Extra hardware is required (hubs or switches) which adds up to the total cost |
| 4. If n nodes are connected to every other node in the network, then the amount of cables required to attach them is n. So, it’s very easy to assemble | 4. Performance is highly predicated on the one device i.e. hub. |
| 5. Fast and simple fault detection because the faulted connections get identified easily | 5. More expensive THAN Bus topology due to the prices of the connecting devices (hub/ switches) |
| 6. It is easy to maintain and robust in nature | 6. This setup requires more cable length |
