|
|
|
All devices have a connection to a central switch or server
|
|
|
They are the most fault tolerant type of network
|
|
|
If one connection fails, only that one device is affected
|
|
|
They can be expensive because of the large amount of cabling needed
|
Detailed explanation-1: -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).
Detailed explanation-2: -Star topology can be more expensive than other topologies. The central hub or switch can be expensive, and the cost of additional devices can add up. This can make star topology less cost-effective for larger networks.
Detailed explanation-3: -Because star topologies need more cables and a central hub, they are more expensive to setup and run because of the increased energy use. Moreover, if the central hub fails, your whole network will fail as well.
Detailed explanation-4: -Mesh Topology Each node is connected to every other mode with a direct link. This topology creates a very reliable network, but requires a large amount of cable and is difficult to administer.
