Network Topology

Network Topology

1. Bus

   • Disadvantages
     • If there are many nodes, Network slows down
     • Data collisions can happen
     • Low security
     • Limited cable lenght
     • If there is a problem in main cable the entire network fails
   • Advantages
     • Easy to install
     • Easy to add extra nodes
     • Uses less cable than star networks
     • Best choice for temporary networks

2. Ring

   • Disadvantages
     • If a one device is turned off the network fails
     • If a cable breaks the network stops working
     • Data goes though EVERY device meaning data is slower than other network layouts
     • If there is a problem in the network it is hard to identify the cause
   • Advantages
     • All data travels in one direction meaning transmission is simple
     • No data collisions
     • Devices can be added easily without the network slowing down

3. Star

   • Disadvantages
     • Costs the most money out all of the networks
     • If the server crashes no-one can use the network
     • Extra hardware may be needed
     • Normally need experts to set-up the network
   • Advantages
     • Star network is the most reliable
     • Good security
     • Little data collisions due to each device has its own cable to the server
