I: the Conception
Excerpt from: Mayo, Keenan and Newcomb, Peter. “How the Web Was Won,” Vanity Fair, July 2008. I: The Conception Paul Baran, an electrical engineer, conceived one of the Internet’s building blocks—packet switching— while working at the Rand Corporation around 1960. Packet switching breaks data into chunks, or “packets,” and lets each one take its own path to a destination, where they are re-assembled (rather than sending everything along the same path, as a traditional telephone circuit does). A similar idea was proposed independently in Britain by Donald Davies. Later in his career, Baran would pioneer the airport metal detector. Paul Baran: It was necessary to have a strategic system that could withstand a first attack and then be able to return the favor in kind. The problem was that we didn’t have a survivable communications system, and so Soviet missiles aimed at U.S. missiles would take out the entire telephone- communication system. At that time the Strategic Air Command had just two forms of communication. One was the U.S. telephone system, or an overlay of that, and the other was high-frequency or shortwave radio. So that left us with the interesting situation of saying, Well, why do the communications fail when the bombs were aimed, not at the cities, but just at the strategic forces? And the answer was that the collateral damage was sufficient to knock out a telephone system that was highly centralized. Well, then, let’s not make it centralized. Let’s spread it out so that we can have other paths to get around the damage.

Computer Network
Computer network A computer network or data network is a telecommunications network that allows computers to exchange data. The connections (network links) between networked computing devices (network nodes) are established using either cable media or wireless media. The best-known computer network is the Internet. Network devices that originate, route and terminate the data are called network nodes. Nodes can include hosts such as servers and personal computers, as well as networking hardware. Two devices are said to be networked when a process in one device is able to exchange information with a process in another device. Computer networks support applications such as access to the World Wide Web, shared use of application and storage servers, printers, and fax machines, and use of email and instant messaging applications. The remainder of this article discusses local area network technologies and classifies them according to the following characteristics: the physical media used to transmit signals, the communications protocols used to organize network traffic, along with the network's size, its topology and its organizational intent. History In the late 1950s, early networks of communicating computers included the military radar system Semi- Automatic Ground Environment (SAGE). In 1960, the commercial airline reservation system semi-automatic business research environment (SABRE) went online with two connected mainframes. In 1962, J.C.R. Licklider developed a working group he called the "Intergalactic Computer Network", a precursor to the ARPANET, at the Advanced Research Projects Agency (ARPA). In 1964, researchers at Dartmouth developed the Dartmouth Time Sharing System for distributed users of large computer systems. The same year, at Massachusetts Institute of Technology, a research group supported by General Electric and Bell Labs used a computer to route and manage telephone connections.

From Packet Switching to the Cloud
Professor Nigel Linge FROM PACKET SWITCHING TO THE CLOUD Telecommunication engineers have always drawn a picture of a cloud to represent a network. Today, however, the cloud has taken on a new meaning, where IT becomes a utility, accessed and used in exactly the same on-demand way as we connect to the National Grid for electricity. Yet, only 50 years ago, this vision of universal access to an all- encompassing and powerful network would have been seen as nothing more than fanciful science fiction. he first electronic, digital, network - a figure that represented a concept of packet switching in which stored-program computer 230% increase on the previous year. data is assembled into a short se- was built in 1948 and This clear and growing demand for quence of data bits (a packet) which heralded the dawning of data services resulted in the GPO com- includes an address to tell the network a new age. missioning in July 1970 an experi- where the data is to be sent, error de- T mental, manual call-set-up, data net- tection to allow the receiver to confirm DATA COMMUNICATIONS 1 work that used modems operating at that the contents of the packet are cor- These early computers were large, 48,000bit/s (48kbit/s). rect and a source address to facilitate cumbersome and expensive machines However, computer communica- a reply. and inevitably a need arose for a com- tions is different to voice communi- Since each packet is self-contained, munication system that would allow cations not only in its form but also any number of them can be transmit- shared remote access to them.

Implications for the Future of Broadband Networks
The Building of the Internet: Implications for the Future of Broadband Networks by Jeffrey A. Hart Department of Political Science Indiana University Bloomington, IN 47405 Internet: [email protected] Robert R. Reed Department of Political Science Indiana University Bloomington, IN 47405 Internet: [email protected] and Francois Bar Berkeley Roundtable on the International Economy University of California Berkeley, CA 94720 Internet: [email protected] August 28, 1992 This paper appeared in _Telecommunications Policy_, November 1992 (Vol. 16, No. 8), and has been nominated for the Donald McGannon Communication Research Center's 1993 Communications Policy Research Award. ABSTRACT The rapid growth of traffic on the Internet, a loosely organized system of interconnected computer networks, suggests a bright fu- ture for switched broadband telecommunications. It also suggests that the path to that future is more likely to involve a broaden- ing of access to broadband networks to users in offices, fac- tories, schools, and homes rather than the transmission of enter- tainment video (high definition or otherwise) via the telephone and cable networks. This article develops the argument by exam- ining the history of the growth of the Internet from its origins in the ARPANET. It describes and explains the transition from ARPANET to the NSFNET in the United States, and discusses the politics behind the National Research and Education Network (NREN) and the gigabit testbeds which will bring broadband capa- bilities to the NSFNET and parts of the Internet. Finally, it examines the forces which are creating pressure for expanding ac- cess to the Internet to schools and libraries, thereby greatly increasing the number of users of the network.

List of Internet Pioneers
List of Internet pioneers Instead of a single "inventor", the Internet was developed by many people over many years. The following are some Internet pioneers who contributed to its early development. These include early theoretical foundations, specifying original protocols, and expansion beyond a research tool to wide deployment. The pioneers Contents Claude Shannon The pioneers Claude Shannon Claude Shannon (1916–2001) called the "father of modern information Vannevar Bush theory", published "A Mathematical Theory of Communication" in J. C. R. Licklider 1948. His paper gave a formal way of studying communication channels. It established fundamental limits on the efficiency of Paul Baran communication over noisy channels, and presented the challenge of Donald Davies finding families of codes to achieve capacity.[1] Charles M. Herzfeld Bob Taylor Vannevar Bush Larry Roberts Leonard Kleinrock Vannevar Bush (1890–1974) helped to establish a partnership between Bob Kahn U.S. military, university research, and independent think tanks. He was Douglas Engelbart appointed Chairman of the National Defense Research Committee in Elizabeth Feinler 1940 by President Franklin D. Roosevelt, appointed Director of the Louis Pouzin Office of Scientific Research and Development in 1941, and from 1946 John Klensin to 1947, he served as chairman of the Joint Research and Development Vint Cerf Board. Out of this would come DARPA, which in turn would lead to the ARPANET Project.[2] His July 1945 Atlantic Monthly article "As We Yogen Dalal May Think" proposed Memex, a theoretical proto-hypertext computer Peter Kirstein system in which an individual compresses and stores all of their books, Steve Crocker records, and communications, which is then mechanized so that it may Jon Postel [3] be consulted with exceeding speed and flexibility.

A Summary of Papers on Fieldexperiments.Com
A SUMMARY OF PAPERS ON FIELDEXPERIMENTS.COM: ALL FIELD EXPERIMENTS POSTED John A. List1 January 2019 Back in 2000, I was moved by Charlie Holt’s website that collated exactly 2000 (mostly) laboratory experiments. That site continues to be quite helpful for my students, colleagues, and me when we have a need to trace the great work that experimentalists have done over the years in the lab. Need insights on multi-unit auctions, “visit Charlie’s site” I often say to my students and colleagues. That site compelled me several years ago to create my own bibliographical site http://www.fieldexperiments.com, which lists publications and discussion papers in experimental economics that make use of the "field" in some manner. The site remains quite active, with an open source that allows scholars to post their own work, and to download hundreds of field experimental papers. With the growth of field experiments, I felt it apropos to provide a site that collated papers using field experiments--both published and working. In my own work I have reserved the term "field experiment" for those cases where I observed subjects in their naturally occurring environments. I explicitly, therefore, discriminated between explorations in this environment and laboratory studies that used non-standard subject pools. In a JEL paper (Harrison and List, 2004), such important differences are accounted for via qualifiers. I followed this nomenclature on the site by placing studies into three groups: 1. Artefactual field experiments, which are the same as conventional lab experiments but with a non-standard subject pool (i.e., non-students).

40-Year Anniversary of Ethernet Celebrated by Nexgen
40-year Anniversary of Ethernet Celebrated by NexGen NexGen Networks, the premier provider of fiber optic-based network solutions to the world’s top financial services firms and global enterprises, marks the invention of Ethernet after forty years as it continues its commitment to Ethernet services. On May 22, 1973, Robert Metcalfe first documented the idea of Ethernet at what was then Xerox's Palo Alto Research Center. The name was inspired by the elegant but long disproven idea of a "lumineferous ether"—an invisible, omnipresent medium through which scientists in the 1800s believed light traveled. Metcalfe and his collaborators decided to in a sense make such a medium a reality, and to use it for the transfer of information through cabling. Ethernet has evolved dramatically since then, and it’s the prevailing standard in Local Area Networks (LANs) today. Nearly all computers and many associated devices ship with an Ethernet connection. NexGen Networks was formed in the New York Metropolitan area ten years ago, which corresponded with a landmark transition of Ethernet from a purely local area technology to a wide area network technology. The need to move larger files faster and the convergence of voice and data onto a single network had drastically increased demand for bandwidth, leading to the proliferation of Ethernet WAN. “NexGen helped to pioneer the building of carrier Ethernet networks with the ability to integrate legacy technologies as an interim step toward delivering end-to-end Ethernet services,” says NexGen’s Jeffrey Barth. “NexGen's expertise with large-scale deployment of the technology strongly positioned it to succeed from the start.
