- 1The computers and other devices are attached to a single backbone. A terminator at each end reflects signals. Signals travel in either direction.Advantages:
They are easy to set up
They are 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 - 2Client 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, therefore 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
- 3Data 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
