   • advantages.
     • 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 or switch first Simple to add or remove a node as it has no effect on any other node Scalability - can add many new nodes.
   • 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
   • definition.
     • a data or communication network in which all nodes are independently connected to one central unit.
