3. Features of a star topology

  • Star networks are very reliable. If one connection fails, it does not affect other users
  • Very few data collisions as each node has its own cable to the server
  • Good security - no workstation can interact with another without going through the server first
  • Simple to add or remove a node as it has no effect on any other node
  • Scalability - can add many new nodes.


  • 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 central switch or server fails, the whole network is down
  • Requires a high performance switch or server in the centre as all traffic passes through it.
