   • Topology
     • Bus Topology
       • connected to one central data line
         • Disadvantages
           • Catastrophic failure
             • Data collisions
           • Advantages
             • cheap
               • easy to add to
       • Ring Topology
         • Where every computer is connected
           • Disadvantages x - data leaks possible. x - catastrophic failure
             • Advantages. -No collisions one way ,and it is cheap
     • Star Topology
       • Connected to one central computer
         • Advantages
           • no data leaks
             • no failure except switch
               • easy to add
                 • a lot faster
         • Disadvantages
           • reliant on a switch
             • Expensive
