Advantages and Disadvantages of a Bus, Ring, Star Network January 11, 2007Posted by Daniaru in Tech.
- Easy to implement and extend
- Well suited for temporary networks (quick setup)
- Initially less expensive than other topologies
- Difficult to administer/troubleshoot.
- Limited cable length and number of stations.
- If there is a problem with the cable, the entire network goes down.
- Maintenance costs may be higher in the long run.
- Performance degrades as additional computers are added or on heavy traffic.
- Low security (all computers on the bus can see all data transmissions).
- One virus in the network will affect all of them (but not as badly as a star or ring network).
- Proper termination is required.(loop must be in closed path).
- If one node fails, the whole network will shut down.
- If many computers are attached, the amount of data flowing causes the network to slow down.
- Data is quickly transferred without a ‘bottle neck’. (very fast, all data traffic is in the same direction)
- The transmission of data is relatively simple as packets travel in one direction only.
- Adding additional nodes has very little impact on bandwidth
- It prevents network collisions because of the media access method or architecture required.
- Data packets must pass through every computer between the sender and recipient therefore this makes it slower.
- If any of the nodes fail then the ring is broken and data cannot be transmitted successfully.
- It is difficult to troubleshoot the ring.
- Because all stations are wired together, to add a station you must shut down the network temporarily.
- In order for all computers to communicate with each other, all computers must be turned on.
- Total dependence upon the one cable
- Good performance
- easy to set up and to expand. Any non-centralised failure will have very little effect on the network, whereas on a ring network it would all fail with one fault
- Expensive to install
- Extra hardware required
