History of the Internet

• Networks prior to the Internet
  • NPL network – a local area computer network operated by a team from the National Physical Laboratory in England, the first to implement packet switching, the design of which influenced other networks that followed.
  • TCP/IP
    protocol suite which later became a technical foundation of the Internet.
  • SATNET – an early satellite packet-switched network, also developed by the Advanced Research Projects Agency, which implemented TCP/IP before the ARPANET.
  • Merit Network – a computer network created in 1966 to connect the mainframe computers at universities that is currently the oldest running regional computer network in the United States.
  • CYCLADES – a French research network created in the early 1970s that pioneered the concept of internetworking by making the hosts responsible for the reliable delivery of data on a packet-switched network, rather than this being a service of the network itself.
  • Computer Science Network (CSNET) – a computer network created in the United States for computer science departments at academic and research institutions that could not be directly connected to ARPANET, due to funding or authorization limitations. It played a significant role in spreading awareness of, and access to, national networking and was a major milestone on the path to development of the global Internet.
  • National Science Foundation Network (NSFNET) – an American networking project, initially created to link researchers to the NSF-funded supercomputing centers that, through further public funding and private industry partnerships, developed into a major part of the early Internet backbone.
• History of Internet components
  • data into packets that are transmitted over a digital network, conceived independently by Paul Baran and Donald Davies
    in the early and mid-1960s.
  • History of communication protocols – the set of rules to enable data communication
    between computers on a network.
  • History of internetworking – networking between computers on different networks.

Internet politics

• data privacy concerning the right to privacy
  from third parties including corporations and governments on the Internet.
• Censorship – the suppression of speech, public communication, or other information, on the basis that such material is considered objectionable, harmful, sensitive, politically incorrect or "inconvenient" as determined by government authorities or by community consensus.
  • freedom of the Press, freedom of speech, and human rights
    .
  • Internet censorship – the control or suppression of what can be accessed, published, or viewed on the Internet enacted by regulators or self-censorship.
    • Content control software
      – a type of software that restricts or controls the content an Internet user is capable to access.
    • Internet censorship and surveillance by country
    • Internet censorship circumvention – the use of techniques and processes to bypass filtering and censored online materials.
• electronic commerce, intellectual property
  in computing, privacy, and freedom of expression.

• Domain name registry or Network Information Center (NIC) – a database of all domain names and the associated registrant information in the top level domains of the Domain Name System of the Internet that allow third party entities to request administrative control of a domain name.
  • ccTLD
    registry.
• Internet Society (ISOC) – an American non-profit organization founded in 1992 to provide leadership in Internet-related standards, education, access, and policy.
• InterNIC (historical) – the organization primarily responsible for Domain Name System (DNS) domain name allocations until 2011 when it was replaced by ICANN.
• Internet Corporation for Assigned Names and Numbers
  (ICANN) – a nonprofit organization responsible for coordinating the maintenance and procedures of several databases related to the namespaces of the Internet, ensuring the network's stable and secure operation.
  • Internet Assigned Numbers Authority (IANA) – a department of ICANN which allocates domain names and maintains IP addresses.
