|
|
If the central switch or server fails, the whole network is down
|
|
|
Requires a high performance switch or server in the centre as all traffic passes through it.
|
|
|
Extra hardware such as hubs and switches may be needed
|
|
|
All 3 of them
|
Detailed explanation-1: -Everything depends on the central device: The central network device determines the performance and number of nodes the network can handle. Highly dependent on the central device: If the hub goes down, everything goes down as none of the devices can work without a hub.
Detailed explanation-2: -Requires more cable than a linear bus . If the connecting network device (network switch) fails, nodes attached are disabled and can’t participate in network communication.
Detailed explanation-3: -Advantages of star topology : More scalable than a peer to peer network or ring network. Easy to add a new station. Easy to install and wiring. Low network traffic.
Detailed explanation-4: -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.
