=Early Internet History=

What later was to become the Internet of today started out in the 1960s, during a time of widespread fear of nuclear warfare.

In 1962, J.C.R. Licklider first proposed the idea for a global network of computers as a way for computers to share research and development in the scientific and military fields, and found the need for better inter-networking when he became head of the US Department of Defense's Advanced Research Projects Agency (DARPA).

To solve the issue of connecting separate physical networks to form one logical network, Leonard Kleinrock developed the idea of packet switching. The idea was that of decentralization to avoid the risk of combat damage compromising the entire network. The first link of Licklider’s DARPA interconnected networking system ARPANET was established in 1969, and ARPANET soon became the technical core of what would become the Internet.

In the following years, other networks such as X.25 and UUCP were established with differing network methods, and a means for unifying them was needed. By 1973, network protocols were hidden by using a common internetwork protocol, and responsibility for reliability was shifted from network to host. With a reduced role of the network, it became possible to join almost any networks together. The first ARPANET connection outside the US was established to Norway’s NORSAR, and then to Great Britain and beyond.

In 1978, TCP/IP protocol emerged in nearly final form.

The first recorded use of the term “Internet” was used in 1974, and it eventually became the Internet as we know it today.
