Nigel's contribution about the internet

Traditional Networks and Internet

  • Centralized
  • Circuit Switching
  • Continuous connection formed
  • Best for real time data(voice)

Problems

Failure of central node can bring down the large parts of the network

Solution

  • Decentralized ( all nodes are equal)
  • Packet switching-(messages broken into parts)-(each packet sent independently)-(Nodes can route data packages efficiently to their destination, avoiding broken/slow nodes on the way

LAN

  • Operated within 1km radius
  • client-server LAN
  • Peer to peer LAN
  • Intranet ( if its set up like the internet)

Wide Area Network

  • Distance over 1km
