network topologies

network topologies

1. Bus network

   • connects devices through a central cable
   • cannot handle large amounts of data
   • fails if main cable is damaged
   • cheap

2. star network

   • expensive
   • can handle large amounts of data
   • all connected to a central hub
   • virus can get to hub quickly
   • if one device fails the others are unaffected

3. mesh network

   • all devices are connected
   • hard to set up
   • expensive
   • data can be transferred easily

4. ring network

   • all devices connected
   • no data collisions
   • cheap to set up
   • viruses can spread easily

5. LAN

   • connects an area e.g. a county
   • expensive
   • easyer to hack than WAN

6. WAN

   • expensive
   • connects a large amount of LANs
   • hard to hack into
   • hard to maintain
