Networks

1. topologies

   • BUS Network
     • advantages
       • cheap to install
         • no collisions
     • disadvantages
       • high chances of catestrophic failure
   • RING Network
     • advantages
       • cheap to install
         • no collisions
     • disadvantages
       • high chance of catestrophic failure
         • if the network fails all the computers go down
   • STAR Network
     • advantages
       • fast. low chance of collisions.
         • easy to add new computers
           • low chance of catestrophic failure
             • if the network goes down. only 1 will be affected. this can easily be fixed
     • disadvantages
       • expensive network
         • failure of networl will take down the whole network

2. types of networks

   • LAN
     • local area network
   • WAN
     • Wide area netwoks

3. internet

   • Mesh Topology
     • mesh topology is a network unlike RING, BUS or STAR Network
       • connecting to more than one nodes in an ad-hoc manner
         • DEFINITION: in a mesh topology there is excellent resiliance as messages can take many different routes to reach a destination
