- Network Topologies
- Bus
- One main cable connects all nodes to each other
- Simple to install and extend
- Failure of one node doesn't affect the rest of the network
- If main bus cable fails entire network is affected
- Lots of data collisions - performance slows with lots of nodes/traffic
- Star
- All devices are connected to a central hub (switch or server)
- Network is unaffected if a device fails
- Simple to add more devices
- No data collisions - better performance than other networks
- Every device needs a cable, can be expensive (if wired network)
- Whole network affected by problems with hub
- Mesh
- Every device is connected to every other device, finds fastest route from one device to another
- No single point where network can fail - always finds alternate route
- Used to be very expensive
- Wireless technology more available - mesh topology more practical now
- All devices connected to each other: full mesh topology
- Not all devices fully connected: partial mesh topology
- Ring
- Makes data pass through every computer in the network in one direction
- Not affected by heavy traffic(one way)
- Cable failure anywhere breaks the network
- Need to break the network to add a new node
- All nodes must be switched on for it to work
- Bus
