History of the Internet

  • Batch Processing

    processing the data one by one
  • Cooled Rooms

    as the size of the computer keeps increasing it needs to be moved to special storages
  • Time Sharing

    spreading the computing power of one computer between multiple users
  • Sputnik 1 Launch

    soviet union launched the first satellite
  • DARPA

    in order to secure US' leading technology and in fear of a missile attack they launched DARPA
  • ARPANET, RAND, NPL, CYCLADES

    DARPA planned a missive computer network to speed things up.
    the scientific and military uses of these became the foundation of modern internet
  • IMP

    IMP took over the network activities while the mainframe only in charge of programs and data files.
    also called IMP subnet
  • TCP

    verifying file transfers
  • Packet Switching

    to avoid congestion the file was divided and put back once it was received
  • Decentralized Network

    in fear of a nuclear attack in 1962 they had to make the network decentralized so if one node is damaged the rest is still usable.
    they used a distribution network to cover long distances with less interferences.
  • Internet

    the focus of Cyclades was communication between nodes
  • Cyclades network

    the nodes just served as transfer nodes instead of interfering with data transfers.
  • X.25 Protocol

    phone companies enabled their services for a small fee
  • ISO

    designed the osi reference model, attempt to standardize the network through it's ends and the channels division into several layers.
  • TCP/IP

    it guarantees compatibility between networks.
  • ARPANET Removed

    Arpanet hardware was removed.
