|
|
|
Requires additional hardware such as the central hub or switch
|
|
|
if the main cable is damaged or fails the whole network fails
|
|
|
More collisions with lots of machines on the network
|
|
|
If the central device fails the whole network goes down.
|
Detailed explanation-1: -So the addition of more devices tends to slow down the entire network. With more devices, there is a risk that collisions will occur within the network, and communication is affected. Speed issues may occur with a larger network using bus topology.
Detailed explanation-2: -Bus architectures are functionally a single link, and any disruption of that link can cause outages for the entire network. Coax-based bus topologies are also difficult to manage, since any change of device location requires some additional planning to find the best place to connect the device to the bus.
Detailed explanation-3: -if there is a problem with the main bus cable, the entire network stops working. as all computers on the bus can see all data that is transmitted, it is not classed as a secure network and can easily be hacked. data collisions are more likely, which causes the network to slow down.
Detailed explanation-4: -Answer: Advantages: Cable required is least compared to other network topologies. Bus topology can be extended easily on either side. Disadvantages: Becomes slow with the increase in number of nodes. Only a single message can travel at a particular time.
