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
