What are advantages of a STAR topology? Performance is consistent even with… Very easy to setup as… No data… .
-Performance is consistent even with heavy network traffic - Very easy to setup as there is simple design • No data collisions
What are disadvantages of a STAR Topology? Expensive due to S and C If the Central switch fails…
• Expensive due to switch and cabling • If the central switch fails, the whole network fails (Single Point Of Failure)
What are advantages of a MESH Topology As the number of nodes increase… (R&S) Nodes do not go through the central switch… If the network is wireless…
• As the number of nodes increase, the reliablity and speed of the network becomes better • Nodes do not go through the central switch, improving speed • If the network is wireless, no cabling cost
What are disadvantages of a MESH Topology? If using a wired network, a large… Maintaining the…
• If using a wired network, a large quanity of cables is required compared to the other topologies. This is expensive • Maintaining the network is difficult
