Cards in this deck (5)

1Bus: The computers and other devices are attached to a single backbone. A terminator is attached at each end to present reflection of signals. Signals travel in either direction.Advantages: Easy to set up, Cheap
Disadvantages: problems with the back bone can bring the whole network down.
Limited distance can be covered.
Many data collisions slow the network down
2Star: Client machines are connected to a central switch or hub, which is usually in turn connected to one or more servers. Signals travel in either direction.Advantages: Problems with a connection do not affect the whole network
Fewer data collisions than bus so faster
Disadvantages: needs more expertise to maintain can be expensive to set up because more building work involved and more network hardware and software needed
3Ring: Data passes through each node, carried in data units called tokens. Traffic is one-way which prevents collisions.Advantages: Very fast - no collisions
Disadvantages: Problems with the backbone can bring the whole network down
Data passes through every node - this makes the network vulnerable to malfunctions
