The Webernet.



  • The internet is a wire. (could be fibreoptic)
  • 2 computers connected directly using this wire are connected
  • Every computer has its ow unique addresses : IP addresses.
  • We associate domain names with IP addresses. "we're only human."-Human Humanson.
  • Files stored on a server on some computer somewhere.
  • Domain Name Service (DNS) : allows you to find domain names and their IP addresses.
  • Computer indirectly connected to the internet are known as clients.
  • To look at the internet: Client goes through DSL to ISP
  • Computers break sent pictures into smaller chunks, called 'packets'.
  • Routers help direct packets to where they need to go.
  • Every time a packet goes through a router it gets IP code added to the address so that it can be returned through the same servers.
  • The packet size is generally 1kB each (1000 or 1024 bytes)
