CYCLADES
The Cyclades (; el, Κυκλάδες, ) are an island group in the Aegean Sea, southeast of mainland Greece and a former administrative prefecture of Greece. They are one of the island groups which constitute the Aegean archipelago. The name refers to the islands ''around'' ("cyclic", κυκλάς) the sacred island of Delos. The largest island of the Cyclades is Naxos, however the most populated is Syros. History The significant Late Neolithic and Early Bronze Age Cycladic culture is best known for its schematic, flat sculptures carved out of the islands' pure white marble centuries before the great Middle Bronze Age Minoan civilization arose in Crete to the south. (These figures have been looted from burials to satisfy a thriving Cycladic antiquities market since the early 20th century.) A distinctive Neolithic culture amalgamating Anatolian and mainland Greek elements arose in the western Aegean before 4000 BCE, based on emmer and wild-type barley, sheep and goats, ...

ARPANET
The Advanced Research Projects Agency Network (ARPANET) was the first wide-area packet-switched network with distributed control and one of the first networks to implement the TCP/IP protocol suite. Both technologies became the technical foundation of the Internet. The ARPANET was established by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense. Building on the ideas of J. C. R. Licklider, Bob Taylor initiated the ARPANET project in 1966 to enable access to remote computers. Taylor appointed Larry Roberts as program manager. Roberts made the key decisions about the network design. He incorporated Donald Davies' concepts and designs for packet switching, and sought input from Paul Baran. ARPA awarded the contract to build the network to Bolt Beranek & Newman who developed the first protocol for the network. Roberts engaged Leonard Kleinrock at UCLA to develop mathematical methods for analyzing the packet network technology. The first ...

History Of The Internet
The history of the Internet has its origin in information theory and the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France. Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. J. C. R. Licklider developed the idea of a universal network at the Information Processing Techniques Office (IPTO) of the United States Department of Defense (DoD) Advanced Research Projects Agency (ARPA). Independently, Paul Baran at the RAND Corporation proposed a distributed network based on data in message blocks in the early 1960s, and Donald Davies conceived o ...

Internet In France
Internet in France has been available to the general public since 1994, but widespread Internet use did not take off until the mid-2000s. As of 31 December 2014, France had 26 million Internet broadband and high-speed connections on fixed networks. In 2014, 80.7% of French households (22.5 million households) had Internet access (47 million users in January 2015, according to Médiamétrie), while 19.3% did not (5.4 million households, out of a total of 27.8 million households). In 2014, 82% of French people aged 12 and over had Internet access at home (even though only 77% used it), and 64% of French people aged 12 years and older connected daily to the Internet from home. Considering all connections locations (not only the home), 83% of French people were Internet users. In metropolitan France, intense competition between Internet service providers has led to the introduction of moderately-priced high speed ADSL up to 28 Mbit/s ( ATM), VDSL2 up to 100 Mbit/s, and FTTX up to 1 Gbi ...

Louis Pouzin
Louis Pouzin (April 20, 1931 in Chantenay-Saint-Imbert, Nièvre, France) is a French computer scientist. He designed an early packet communications network, CYCLADES. This network was the first actual implementation of the pure datagram model, initially conceived and described by Donald Davies, subsequently named by Halvor Bothner-By, and seen by Louis Pouzin as his personal invention. His work, and that of his colleagues Hubert Zimmerman and Gérard Le Lann, were acknowledged by Vinton Cerf as substantial contributions to the design of TCP/IP, the protocol suite used by the Internet. Biography He studied at the École Polytechnique from 1950 to 1952. Having participated in the design of the Compatible Time-Sharing System (CTSS) at MIT, Pouzin wrote a program for it called RUNCOM around 1963–64. RUNCOM permitted the execution of commands contained within a folder and can be considered the ancestor of the command-line interface and shell scripts. Pouzin was the one who coin ...
