NETWORKS

1. Network topologies

   • Bus
     • Advantages
       • Easy to install
       • Easy to add extra workstations
       • Uses less cable than a star network
       • Best choice for temporary networks
     • Disadvantages
       • If the central cable fails, the entire network stops working
       • Data can travel slowly if there are lots of workstations connected and data collisions can occur
       • Low security- every workstation can see all the data in a network
       • Limited cable length and maximum number of workstations
   • Ring
     • Advantages
       • Transmission of data only travels in one direction
       • No data collisions
       • extra computers can be added with little effect on the performance
     • Disadvantages
       • If a machine is switched off, network doesn't work
       • If a cable breaks, the system shuts down
