networks

1. type of networks

   • bus
     • advantages
       • cheap to install
     • disadvantages
       • high chance of catastrophic failure
       • lots of colisions
       • slows down as more computers are needed
   • ring
     • disadvantages
       • high chance of catastrophic failure
       • difficult to expand
     • advantages
       • cheap to install
       • no collisions
   • star
     • disadvantages
       • expensive
       • depends on a switch
     • fast
       • low chance of catastrophic failure
         • easy to add new computers

2. IP adress

   • An IP adress is a unique value given to every computer on a network, used to identify it.
   • a bit binary code

3. WAN

   • wide area network

4. LAN

   • large area network

5. internet

   • packets
     • Data is split into small chunks called packets
   • routing
     • the packets are always sent down the lowest cost route
     • route finding algorithms are used to find the lowest cost route
   • mesh topology
     • the mesh topology makes sure the internet can never be broken because there will always be another route.
     • multiple connections between devices
