List Of Internet Pioneers
Instead of having a single "inventor", the Internet was developed by many people over many years. The following are some Internet pioneers who contributed to its early and ongoing development. These include early theoretical foundations, specifying original protocols, and expansion beyond a research tool to wide deployment. The pioneers Claude Shannon Claude Shannon (1916–2001) called the "father of modern information theory", published "A Mathematical Theory of Communication" in 1948. His paper gave a formal way of studying communication channels. It established fundamental limits on the efficiency of communication over noisy channels, and presented the challenge of finding families of codes to achieve capacity. Vannevar Bush Vannevar Bush (1890–1974) helped to establish a partnership between U.S. military, university research, and independent think tanks. He was appointed Chairman of the National Defense Research Committee in 1940 by President Franklin D. Roosevelt, app ...

Internet
The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. It is a '' network of networks'' that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing. The origins of the Internet date back to the development of packet switching and research commissioned by the United States Department of Defense in the 1960s to enable time-sharing of computers. The primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1970s to enable resource shari ...

Man-Computer Symbiosis
"Man-Computer Symbiosis" is the title of a work by J.C.R. Licklider, which was published in 1960. The paper represented what we would today consider a fundamental, or key text of the modern computing revolution. The work describes something of Lickliders' vision for a complementary (symbiotic) relationship between humans and computers at a potential time of the future. According to ''Bardini'', Licklider envisioned a future time when machine cognition (''cerebration'') would surpass and become independent of human direction, as a basic stage of development within human evolution. ''Jacucci'' gives the description of Lickliders' vision as being the ''very tight coupling of human brains and computing machines'' (c.f. ''brain'', the term '' cohesion'' & the general definitions of the term '' coupling''). As a necessary ''pre-requisite'' of human-computer symbiosis, Licklider conceived of a thing known as the ''Thinking centre''. Altogether these things were pre-conditions for ...

NPL Network
The NPL network, or NPL Data Communications Network, was a local area computer network operated by a team from the National Physical Laboratory in London that pioneered the concept of packet switching. Based on designs first conceived by Donald Davies in 1965, development work began in 1968. Elements of the first version of the network, the Mark I, became operational during 1969 then fully operational in January 1970, and the Mark II version operated from 1973 until 1986. The NPL network and the ARPANET in the United States were the first two computer networks that implemented packet switching and the NPL network was the first to use high-speed links. Origins In 1965, Donald Davies, who was later appointed to head of the NPL Division of Computer Science, proposed a commercial national data network based on packet switching in ''Proposal for the Development of a National Communications Service for On-line Data Processing''. After the proposal was not taken up nationally, during ...

Lawrence Roberts (scientist)
Lawrence Gilman Roberts (December 21, 1937 – December 26, 2018) was an American engineer who received the Draper Prize in 2001 "for the development of the Internet", and the Principe de Asturias Award in 2002. As a program manager and later office director at the Advanced Research Projects Agency, Roberts and his team created the ARPANET using packet switching techniques invented by British computer scientist Donald Davies and American Paul Baran. The ARPANET, which was built by the Massachusetts-based company Bolt Beranek and Newman (BBN), was a predecessor to the modern Internet. He asked Leonard Kleinrock to apply mathematical models to simulate the performance of the network. Roberts later served as CEO of the commercial packet-switching network Telenet. Early life and education Roberts, who was known as Larry, was born and raised in Westport, Connecticut. He was the son of Elizabeth (Gilman) and Elliott John Roberts, both of whom had doctorates in chemistry. It is said t ...

Symposium On Operating Systems Principles
In ancient Greece, the symposium ( grc-gre, συμπόσιον ''symposion'' or ''symposio'', from συμπίνειν ''sympinein'', "to drink together") was a part of a banquet that took place after the meal, when drinking for pleasure was accompanied by music, dancing, recitals, or conversation.Peter Garnsey, ''Food and Society in Classical Antiquity'' (Cambridge University Press, 1999), p. 13online Sara Elise Phang, ''Roman Military Service: Ideologies of Discipline in the Late Republic and Early Principate'' (Cambridge University Press, 2008), pp. 263–264. Literary works that describe or take place at a symposium include two Socratic dialogues, Plato's ''Symposium'' and Xenophon's ''Symposium'', as well as a number of Greek poems such as the elegies of Theognis of Megara. Symposia are depicted in Greek and Etruscan art that shows similar scenes. In modern usage, it has come to mean an academic conference or meeting such as a scientific conference. The equivalent of a Gree ...

Datagram
A datagram is a basic transfer unit associated with a packet-switched network. Datagrams are typically structured in header and payload sections. Datagrams provide a connectionless communication service across a packet-switched network. The delivery, arrival time, and order of arrival of datagrams need not be guaranteed by the network. History In the early 1970s, the term ''datagram'' was created by combining the words ''data'' and ''telegram'' by the CCITT rapporteur on packet switching, Halvor Bothner-By. While the word was new, the concept had already a long history. In 1962, Paul Baran described, in a RAND Corporation report, a hypothetical military network having to resist a nuclear attack. Small standardized "message blocks", bearing source and destination addresses, were stored and forwarded in computer nodes of a highly redundant meshed computer network. "The network user who has called up a "virtual connection" to an end station and has transmitted messages ... ...

Communication Protocol
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics (computer science), semantics and synchronization of communication and possible Error detection and correction, error recovery methods. Protocols may be implemented by Computer hardware, hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses pre-determined for that particular situation. The specified behavior is typically independent of how it is to be Implementation, implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, ...

Router (computing)
A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions between networks and on the global Internet. Data sent through a network, such as a web page or email, is in the form of data packets. A packet is typically forwarded from one router to another router through the networks that constitute an internetwork (e.g. the Internet) until it reaches its destination node. A router is connected to two or more data lines from different IP networks. When a data packet comes in on one of the lines, the router reads the network address information in the packet header to determine the ultimate destination. Then, using information in its routing table or routing policy, it directs the packet to the next network on its journey. The most familiar type of IP routers are home and small office routers that simply forward IP packets between the home computers and the Internet. More sophisticated routers, ...

Packet Switching
In telecommunications, packet switching is a method of grouping Data (computing), data into ''network packet, packets'' that are transmitted over a digital Telecommunications network, network. Packets are made of a header (computing), header and a payload (computing), payload. Data in the header is used by networking hardware to direct the packet to its destination, where the payload is extracted and used by an operating system, application software, or protocol suite, higher layer protocols. Packet switching is the primary basis for data communications in computer networks worldwide. In the early 1960s, American computer scientist Paul Baran developed the concept that he called "distributed adaptive message block switching", with the goal of providing a fault-tolerant, efficient routing method for telecommunication messages as part of a research program at the RAND Corporation, funded by the United States Department of Defense. His ideas contradicted then-established principles ...
