- Network topologies
- Star topology
- All the devices are connected to a central switch
- Central switch
- Allows many devices to access the server at the same time
- Pros
- If a device fails the rest of the network is unaffected
- It's simple to add more devices to the network
- Better performance
- Cons
- Cables are expensive
- If the server has a problem then the whole network is affected
- Bus topology
- All devices arranged in a line
- Devices send data in both directions causing data collisions
- Ring topology
- Data moves in one direction
- Only one device can send data at a time and data passes through all devices
- Mesh topology
- It has no central device
- Every device is either directly or indirectly connected
- Work by sending data along the fastest route
- If one device fails then data is sent along a different route
- They are very expensive
- Full mesh
- Every device is connected to every other device
- Partial mesh
- Not all devices are fully-connected
- Star topology
