Task 5

Star

Pros

Better...Performance Isolation of devices...Benefits from centralization

Cons

High dependence on the system...Network size is limited...Wiring up of the system can be very complex

Bus

Pros

Easy to implement and extend...Cheaper than other technologies...Cost effective as only a single cable is used

Cons

Limited cable length and number of stations...Maintenance costs may be higher in the long run...It is slower than the other topologies

Ring

Pros

Very orderly network where every device has access to the token and the opportunity to transmit...Can create much larger network using token ring...Performs better than a star topology under heavy network load

Cons

Moves, adds and changes of devices can affect the network...Much slower than an Ethernet network under normal load...Network adapter cards and MAU’S are much more expensive than Ethernet cards and hubs
