Network

Network

1. Star Topology

   • Security
     • All data runs through switch (weak point
     • Only switch can access all data
       • single computer being hacked doesn't damaging th whole net
   • Reliability
     • Wire failurs dont take down network
     • computer failure doesnt take down network
     • Weak to server failure if switch breaks
   • Scale-ability
     • Simple to add more connections to network
     • Few colisions
       • Only if data is sent in both directions at once

2. Bus Network

   • All data transfered by one wire
   • Poor scale-ability
     • Collisions between data packets
     • possibility of faults increase expenentally with size
       • Slows down
   • Un-reliable
     • Single fault can destroy Network
   • Security weakness
     • All computers can access data that's transferd by the wire

3. Mesh Topology

   • Highly scaleable
     • This is the internet
     • Multiple paths to any destination
       • Singular failures don't bring down the Network
   • full mesh is expensive
   • Part mesh is usally used to keep costs down
   • Security risk
     • Hard to protect VS tracking from bi-passed computers
     • don't know what path the system takes
       • Hard to control
