Resource summary

Network Topology
1 Bus
1.1 Disadvantages
1.1.1 If there are many nodes, Network slows down
1.1.2 Data collisions can happen
1.1.3 Low security
1.1.4 Limited cable lenght
1.1.5 If there is a problem in main cable the entire network fails
1.2 Advantages
1.2.1 Easy to install
1.2.2 Easy to add extra nodes
1.2.3 Uses less cable than star networks
1.2.4 Best choice for temporary networks
2 Ring
2.1 Disadvantages
2.1.1 If a one device is turned off the network fails
2.1.2 If a cable breaks the network stops working
2.1.3 Data goes though EVERY device meaning data is slower than other network layouts
2.1.4 If there is a problem in the network it is hard to identify the cause
2.2 Advantages
2.2.1 All data travels in one direction meaning transmission is simple
2.2.2 No data collisions
2.2.3 Devices can be added easily without the network slowing down
3 Star
3.1 Disadvantages
3.1.1 Costs the most money out all of the networks
3.1.2 If the server crashes no-one can use the network
3.1.3 Extra hardware may be needed
3.1.4 Normally need experts to set-up the network
3.2 Advantages
3.2.1 Star network is the most reliable
3.2.2 Good security
3.2.3 Little data collisions due to each device has its own cable to the server
