Give two advantages and disadvantages of BUS, Ring and Tree topology.
Ans. BUS topology advantages:
Length of the cable is small.
Layout of the cable is very simple.
Disadvantages:
Fault in the backbone cable can upset the function of the whole network.
Fault diagnosis is difficult.
Ring Topology:
it is characterized by data flow around the ring on one or two direction. Sharing the ring through token, each node being connected to its neighboring node.
Short cable length and less connection will be needed which increase network reliability.
Disadvantage:
Since each node in this network connected to its neighbouring node and data is travel through each node. There is one traffic flow until defective node is removed. This causes network failure.
in this topology this is difficult to diagnoses fault and re- configure network is also difficult.
Tree Topology:
Suitable for hierarchical flow of data.
This make it easier to isolate a defective bode.
Disadvantages:
Low speed. The data transmission is slow.
Fault isolation is difficult.
