- 1State Two Network DevicesRouter: connects the network to other networks (i.e internet)
- 2Coaxial Twisted Pair Fiber OpticCoaxial - cheap and nosily
Twisted Pair - Medium
Optical - Fast and Expensive - 3LAN - CharacteristicsLocal Area Network - Fast - Good connection - within one building
- 4WAN - CharacterisitcsWide Area Network - Slower - Global range (internet)
- 5Network TopographyBus is cheap but easy to break (fault) star has expensive hardware but is more resilient to fault as each node connects to the center.
- 6ProtocolsHttp --> send audio video
impar --> emails
ftp --> files
voip --> voice
ip --> ip - 7Http, HttpsHttps is secured by encryption, that is to obscure the messages so than only the intended recipient can read the message
- 8ipv4 ipv6Ipv6 has six sets of numbers to uniquely identify an internet address, ipv4 is old and has few possible combinations and will eventually be replaced by ipv6
- 9Wired vs WirelessWired network Faster speed, better connection, must be plugged in not at all portable.
Wireless free of wires, easier to add new users, slows down as more users are added, limited range connections prone to interference and dropping connections - 10VPNVirtual private Network, bridges two networks together to virtually appears as one.
