There is the social aspect, which resulted in a broad community of Internauts working together to create and evolve the technology.And there is the commercialization aspect, resulting in an extremely effective transition of research results into a broadly deployed and available information infrastructure.

In spirit, the concept was very much like the Internet of today.

Licklider was the first head of the computer research program at DARPA, starting in October 1962.

Much material currently exists about the Internet, covering history, technology, and usage.

A trip to almost any bookstore will find shelves of material written about the Internet.

The invention of the telegraph, telephone, radio, and computer set the stage for this unprecedented integration of capabilities.

The Internet is at once a world-wide broadcasting capability, a mechanism for information dissemination, and a medium for collaboration and interaction between individuals and their computers without regard for geographic location.The Internet today is a widespread information infrastructure, the initial prototype of what is often called the National (or Global or Galactic) Information Infrastructure.Its history is complex and involves many aspects – technological, organizational, and community.Leonard Kleinrock at MIT published the first paper on packet switching theory in July 1961 and the first book on the subject in 1964.Kleinrock convinced Roberts of the theoretical feasibility of communications using packets rather than circuits, which was a major step along the path towards computer networking.The other key step was to make the computers talk together.To explore this, in 1965 working with Thomas Merrill, Roberts connected the TX-2 computer in Mass.At the conference where he presented the paper, there was also a paper on a packet network concept from the UK by Donald Davies and Roger Scantlebury of NPL.Scantlebury told Roberts about the NPL work as well as that of Paul Baran and others at RAND.The word “packet” was adopted from the work at NPL and the proposed line speed to be used in the ARPANET design was upgraded from 2.4 kbps to 50 kbps.In August 1968, after Roberts and the DARPA funded community had refined the overall structure and specifications for the ARPANET, an RFQ was released by DARPA for the development of one of the key components, the packet switches called Interface Message Processors (IMP’s).
