   • Ring. This is a LAN network which means it can only be accessed from within the building
     • Faster speeds are possible because of uni direction
     • The faults are difficult to locate
   • Star. This network is a client server and the file server is in the center of the spokes with peripherals and work stations on the end of each spoke
     • Easy to add extra computers without disturbing the network
     • High cable cost makes this the most expensive topology
   • Bus/Ethernet

   • Peer to Peer
     • Advantages

       • Network manager is not needed
       • All machines have the same status
       • Network size -only for smaller groups
