Networking

1. Network Topologies

   • Bus topoligies
     • Advantages
       • Easy to connect a computer or peripheral to a linear bus.
       • Requires less cable length than a star topology.
       • Easy to install
       • Easy to add extra workstations
       • Best choice for temporary networks.
     • Disadvantages
       • Entire network shuts down if there is a break in the main cable.
       • If there are a lot of workstations on the network, data can travel slowly.
       • Data collisions can happen as the network becomes busy
       • Low security - every workstation can see all of the data in the network
       • Limited cable length and a maximum number of workstations.
   • Star Topoligies
     • Advantages
       • Star networks are very reliable. If one connection fails, it does not affect other users
       • Very few data collisions as each workstation has its own cable to the server
       • Good security - no workstation can interact with another without going through the server first
     • Disadvantages
       • The most expensive network layout to install because of the amount of cables needed
       • Installing the network usually needs experts to set it up
       • Extra hardware such as hubs and switches may be needed
       • If the server crashes or stops working then nobody will be able to access their files or use the network.
   • Ring topologies
