Question

what are the advantages and disadvantages of star topology over tree topology​

Answer 1

Answer:

Disadvantages of a Star Topology

Requires more cable length than a linear topology. If the hub, switch, or concentrator fails, nodes attached are disabled. More expensive than linear bus topologies because of the cost of the hubs, etc.

Answer 2

Advantages of Star Topology

• Easy to install and wire.

• No disruptions to the network when connecting or removing devices

• Easy to detect faults and to remove parts.

Disadvantages of Star Topology

• Requires more cable length than a linear bus topology.

• If the connecting network device (network switch) fails, nodes attached are disabled and cannot participate in computer network communication.

• More expensive than linear bus topology because of the cost of the connecting devices (network switches).

-------------------------------------------------------------

Advantages of Tree Topology

-It is a combination of bus and star topology

-It provides high scalability, as leaf nodes can add more nodes in the hierarchical chain.

-Other nodes in a network are not affected, if one of their nodes get damaged

Disadvantages of tree topology

-Large cabling is required as compared to star and bus topology.

-On the failure of a hub, the entire network fails.

-Tree network is very difficult to configure than other network topologies.
