Don Cone
Virgil Donald Cone (October 17, 1926 – April 7, 2011) was a technician and later researcher at SRI International who developed and ran the Packet Radio Van that was used in the first ARPANET internetworked transmission. Early life and education Cone dedicated his early life to the study of photography, in particular at the Fred Archer School of Photography under Fred R. Archer, who was a partner of Ansel Adams. Cone served in the United States Army Air Corps for about a year near the end of World War II; he broke his wrist during basic training and was hospitalized in Coral Gables, Florida, and was reassigned as a medical photographer in that hospital. After he was discharged, he worked for a commercial photographer in Pasadena, California. Early career Around 1950, Don joined the Jet Propulsion Laboratory in Pasadena, California as a technician in order to better financially support his family.

Inglewood, California
Inglewood is a city in southwestern Los Angeles County, California, in the Los Angeles metropolitan area. As of the 2020 U.S. Census, the city had a population of 107,762. It was incorporated on February 14, 1908. The city is in the South Bay region of Los Angeles County, near Los Angeles International Airport. History The earliest residents of what is now Inglewood were Native Americans who used the Aguaje de Centinela natural springs in today's Edward Vincent Jr. Park (known for most of its history as Centinela Park). Local historian Gladys Waddingham wrote that these springs took the name Centinela from the hills that rose gradually around them, and which allowed ranchers to watch over their herds," (thus the name ''centinelas ''or sentinels). Spanish era The original settlers of Los Angeles in 1781, one of whom was Spanish soldier Jose Manuel Orchado Machado, "a 23-year-old muleteer from Los Alamos in Sinaloa". These settlers, she wrote, were ordered by the offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

LSI-11
The PDP-11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation (DEC) from 1970 into the 1990s, one of a set of products in the Programmed Data Processor (PDP) series. In total, around 600,000 PDP-11s of all models were sold, making it one of DEC's most successful product lines. The PDP-11 is considered by some experts to be the most popular minicomputer. The PDP-11 included a number of innovative features in its instruction set and additional general-purpose registers that made it much easier to program than earlier models in the PDP series. Further, the innovative Unibus system allowed external devices to be easily interfaced to the system using direct memory access, opening the system to a wide variety of peripherals. The PDP-11 replaced the PDP-8 in many real-time computing applications, although both product lines lived in parallel for more than 10 years. The ease of programming of the PDP-11 made it very popular for general-purpose computing uses also. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internet Protocol Suite
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the suite are the Transmission Control Protocol (TCP), the User Datagram Protocol (UDP), and the Internet Protocol (IP). In the development of this networking model, early versions of it were known as the Department of Defense (DoD) model because the research and development were funded by the United States Department of Defense through DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed, and received. This functionality is organized into four abstraction layers, which classify all related protocols according to each protocol's scope of networking. An implementation of the layers for a particular application forms a protocol stack. From lowest to high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internetworking
Internetworking is the practice of interconnecting multiple computer networks, such that any pair of hosts in the connected networks can exchange messages irrespective of their hardware-level networking technology. The resulting system of interconnected networks are called an ''internetwork'', or simply an ''internet''. The most notable example of internetworking is the Internet, a network of networks based on many underlying hardware technologies. The Internet is defined by a unified global addressing system, packet format, and routing methods provided by the Internet Protocol. The term ''internetworking'' is a combination of the components ''inter'' (between) and ''networking''. An earlier term for an internetwork is catenet, a short-form of ''(con)catenating networks''. Interconnection of networks Internetworking started as a way to connect disparate types of networking technology, but it became widespread through the developing need to connect two or more local area network ...

Packet Radio
In digital radio, packet radio is the application of packet switching techniques to digital radio communications. Packet radio uses a packet switching protocol as opposed to circuit switching or message switching protocols to transmit digital data via a radio communication link. Packet radio can be differentiated from other digital radio switching schemes by the following attributes: * Transmitted data is broken into packets, each of which contains a destination (and typically the source) address * A transmitted message may be broken into a sequence of packets before transmission, which are then re-assembled into the original message upon reception * Packets for multiple destinations can be transmitted on the same radio link in an asynchronous fashion * A packet may be addressed to all possible recipients rather than a specific one (broadcast) * A packet may be stored and subsequently forwarded towards its destination by a network node This is very similar to how packets of data ...

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource ''The Economist'' has called DARPA the agency "that shaped the modern world," and pointed out that "Moderna COVID-19 vaccine, Moderna's COVID-19 vaccine sits alongside weather satellites, Global Positioning System, GPS, Unmann ...
