Network topologies

Network topologies

1. what is a topologie

   • a network topologie is the lay out of nodes

2. types of topologies

   • star topologie
     • advantages
       • if a node fails it does not effect another node
       • new nodes can be added easily
       • fewer data collisions can occur
     • disadvantages
       • the whole network can be effected when the central point goes down
       • wired star networks can be expensive
   • mesh topologie
     • advantages
       • communications can be received more quickly if the route to the intended recipient is short
       • communications should always get through as there are many possible routes
       • as there are multiple connections and no central node, a node should not become isolated
     • disadvantages
       • many connections would mean a lot more maintenance is needed

3. parts of topologies

   • nodes
   • servers
   • switch
   • ethernet cables
