SRI International
–
SRI International is an American nonprofit research institute headquartered in Menlo Park, California. The trustees of Stanford University established SRI in 1946 as a center of innovation to support development in the region. The organization was founded as the Stanford Research Institute, SRI formally separated from Stanford University in 1970 and became known as SRI International in 1977. SRI describes its mission as creating world-changing solutions to make people safer, healthier and it performs client-sponsored research and development for government agencies, commercial businesses, and private foundations. It also licenses its technologies, forms strategic partnerships, sells products, SRIs annual revenue in 2014 was approximately $540 million. SRIs headquarters are located near the Stanford University campus, jeffrey has served as SRIs president and CEO since September 2014. Sarnoff Corporation, an owned subsidiary of SRI since 1988, was fully integrated into SRI in January 2011. SRI has received more than 4,000 patents and patent applications worldwide, in the 1920s, Stanford University professor Robert E. Swain proposed creating a research institute in the Western United States. Herbert Hoover, then a trustee of Stanford University, was also a proponent of an institute. The development of the institute was delayed by the Great Depression in the 1930s and World War II in the 1940s, with three separate attempts leading to its formation in 1946. In August 1945, Maurice Nelles, Morlan A. Visel, a second attempt was made by Henry T. Heald, then president of the Illinois Institute of Technology. In 1945, Heald wrote a report recommending a research institute on the West Coast, a third attempt was made by Fred Terman, Stanford Universitys dean of engineering. Termans proposal followed Healds, but focused on faculty and student research more than contract research, the trustees of Stanford University voted to create the organization in 1946. It was structured so that its goals were aligned with the charter of the university—to advance scientific knowledge and to benefit the public at large, not just the students of Stanford University. The trustees were named as the general members, and elected SRIs directors, if the organization were dissolved. Research chemist William F. Talbot became the first director of the institute and this and other issues, including frustration with Tresidders micromanagement of the new organization, caused Talbot to repeatedly offer his resignation, which Tresidder eventually accepted. Talbot was replaced by Jesse Hobson, who had led the Armour Research Foundation. SRIs first research project investigated whether the plant could be used as a source of natural rubber

PDP-11
–
The PDP-11 is a series of 16-bit minicomputers sold by Digital Equipment Corporation from 1970 into the 1990s, one of a succession of products in the PDP series. The PDP-11 had several innovative features, and was easier to program than its predecessors through the additional general-purpose registers. The PDP-11 replaced the PDP-8 in many applications, although both product lines lived in parallel for more than 10 years. In total, around 600,000 PDP-11s of all models were sold and its successor in the mid-range minicomputer niche was the 32-bit VAX-11, named as a nod to the PDP-11s popularity. The PDP-11 is considered by experts to be the most popular minicomputer ever. Design features of the PDP-11 influenced the design of most late-1970s computer systems including the Intel x86, design features of PDP-11 operating systems, as well as other operating systems from Digital Equipment, influenced the design of other operating systems such as CP/M and hence also MS-DOS. For a decade, the PDP-11 was the smallest system that could run Unix and it is commonly stated that the C programming language took advantage of several low-level PDP-11–dependent programming features, albeit not originally by design. In 1967–68, DEC engineers designed a 16-bit, word-addressed machine, management cancelled the project and some of the engineers later left DEC and produced it as the Data General Nova. A subsequent effort, code-named Desk Calculator, looked at a variety of options before choosing what became the 16-bit PDP-11, DECs previous PDP-8 and PDP-9 had 12- and 18-bit words, the PDP-11 family was announced in January 1970 and shipments began early that year. DEC sold over 170,000 PDP-11s in the 1970s, initially manufactured of small-scale transistor–transistor logic, a single-board large scale integration version of the processor was developed in 1975. A two-or-three-chip processor, the J-11 was developed in 1979, the last models of the PDP-11 line were the PDP-11/94 and -11/93 introduced in 1990. The PDP-11 processor architecture has an orthogonal instruction set. For example, instead of such as load and store. More complex instructions such as add likewise can have memory, register, input, most operands can apply any of eight addressing modes to eight registers. The addressing modes provide register, immediate, absolute, relative, deferred, and indexed addressing, use of relative addressing lets a machine-language program be position-independent. Early models of the PDP-11 had no dedicated bus for input/output, an input/output device determined the memory addresses to which it would respond, and specified its own interrupt vector and interrupt priority. DEC openly published the basic Unibus specifications, even offering prototyping bus interface circuit boards, the Unibus made the PDP-11 suitable for custom peripherals. Higher-performance members of the PDP-11 family, starting with the PDP-11/45 Unibus and 11/83 Q-bus systems, instead, memory was interfaced by dedicated circuitry and space in the CPU cabinet, while the Unibus continued to be used for I/O only

Portola Valley is an incorporated town in San Mateo County, California, United States. It is one of the top 10 wealthiest ZIP codes in the United States, considered one of the most elite towns in America, Portola Valley has a population of just under 5,000 people. Portola Valley is one of the forty wealthiest towns in the United States, within the State of California, Portola Valley is ranked as the sixth wealthiest place. The zip code 94028, which encompasses the whole of Portola Valley, has the 9th most expensive housing prices within the country according to Forbes Magazine 2013, the population was 4,353 at the 2010 census. Portola Valley was named for Spanish explorer Gaspar de Portolá, who led the first party of Europeans to explore the San Francisco Peninsula in 1769, the town was officially incorporated in 1964. The towns long history back to 1834, when land was used for the Rancho Corte de Madera primarily for cattle grazing. Another place of interest within the town was the Searsville area, searsvilles redwood trees were logged and used for building housing. Evidence of logging can be seen by walking through the preserve, Portola Valley has also been included many times on lists of Americas wealthiest ZIP codes. Initially, Portola Valley was a vacation community for wealthy San Franciscans who would make trips down during the summer in horse. Below is a sample of the many spots on elite ZIP code lists Portola Valley has earned. Note that years when 94028 has cracked the top 10 most expensive ZIP codes on a level have been highlighted in bold. The Windy Hill Open Space Preserve is on the towns southwest side and it is off Interstate 280, near Woodside, just west of Palo Alto and Los Altos and south of Menlo Park, and is in a mostly wooded area, with some open plains. Portola Valley can generally be divided into 5 subdivisions, Central Portola Valley, The Ranch, Corte Madera, Los Trancos/Vista Verde, and Blue Oaks. According to the United States Census Bureau, the town has an area of 9.1 square miles,99. 98% of it land and 0. 02% of it water. Villa Lauriston was initially commisioned by the founder of Fairmont Hotels, the 2010 United States Census reported that Portola Valley had a population of 4,353. The population density was 478.7 people per square mile, the racial makeup of Portola Valley was 3,960 White,12 African American,5 Native American,242 Asian,1 Pacific Islander,29 from other races, and 104 from two or more races. Hispanic or Latino of any race were 175 persons, the Census reported that 4,309 people lived in households,9 lived in non-institutionalized group quarters, and 35 were institutionalized. There were 37 unmarried opposite-sex partnerships, and 21 same-sex married couples or partnerships,420 households were made up of individuals and 290 had someone living alone who was 65 years of age or older

Internet
–
The Internet is the global system of interconnected computer networks that use the Internet protocol suite to link devices worldwide. The origins of the Internet date back to research commissioned by the United States federal government in the 1960s to build robust, the primary precursor network, the ARPANET, initially served as a backbone for interconnection of regional academic and military networks in the 1980s. Although the Internet was widely used by academia since the 1980s, Internet use grew rapidly in the West from the mid-1990s and from the late 1990s in the developing world. In the two decades since then, Internet use has grown 100-times, measured for the period of one year, newspaper, book, and other print publishing are adapting to website technology, or are reshaped into blogging, web feeds and online news aggregators. The entertainment industry was initially the fastest growing segment on the Internet, the Internet has enabled and accelerated new forms of personal interactions through instant messaging, Internet forums, and social networking. Business-to-business and financial services on the Internet affect supply chains across entire industries, the Internet has no centralized governance in either technological implementation or policies for access and usage, each constituent network sets its own policies. The term Internet, when used to refer to the global system of interconnected Internet Protocol networks, is a proper noun. In common use and the media, it is not capitalized. Some guides specify that the word should be capitalized when used as a noun, the Internet is also often referred to as the Net, as a short form of network. Historically, as early as 1849, the word internetted was used uncapitalized as an adjective, the designers of early computer networks used internet both as a noun and as a verb in shorthand form of internetwork or internetworking, meaning interconnecting computer networks. The terms Internet and World Wide Web are often used interchangeably in everyday speech, however, the World Wide Web or the Web is only one of a large number of Internet services. The Web is a collection of interconnected documents and other web resources, linked by hyperlinks, the term Interweb is a portmanteau of Internet and World Wide Web typically used sarcastically to parody a technically unsavvy user. The ARPANET project led to the development of protocols for internetworking, the third site was the Culler-Fried Interactive Mathematics Center at the University of California, Santa Barbara, followed by the University of Utah Graphics Department. In an early sign of growth, fifteen sites were connected to the young ARPANET by the end of 1971. These early years were documented in the 1972 film Computer Networks, early international collaborations on the ARPANET were rare. European developers were concerned with developing the X.25 networks, in December 1974, RFC675, by Vinton Cerf, Yogen Dalal, and Carl Sunshine, used the term internet as a shorthand for internetworking and later RFCs repeated this use. Access to the ARPANET was expanded in 1981 when the National Science Foundation funded the Computer Science Network, in 1982, the Internet Protocol Suite was standardized, which permitted worldwide proliferation of interconnected networks.5 Mbit/s and 45 Mbit/s. Commercial Internet service providers emerged in the late 1980s and early 1990s, the ARPANET was decommissioned in 1990

London
–
London /ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames in the south east of the island of Great Britain and it was founded by the Romans, who named it Londinium. Londons ancient core, the City of London, largely retains its 1. 12-square-mile medieval boundaries. London is a global city in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism. It is crowned as the worlds largest financial centre and has the fifth- or sixth-largest metropolitan area GDP in the world, London is a world cultural capital. It is the worlds most-visited city as measured by international arrivals and has the worlds largest city airport system measured by passenger traffic, London is the worlds leading investment destination, hosting more international retailers and ultra high-net-worth individuals than any other city. Londons universities form the largest concentration of education institutes in Europe. In 2012, London became the first city to have hosted the modern Summer Olympic Games three times, London has a diverse range of people and cultures, and more than 300 languages are spoken in the region. Its estimated mid-2015 municipal population was 8,673,713, the largest of any city in the European Union, Londons urban area is the second most populous in the EU, after Paris, with 9,787,426 inhabitants at the 2011 census. The citys metropolitan area is the most populous in the EU with 13,879,757 inhabitants, the city-region therefore has a similar land area and population to that of the New York metropolitan area. London was the worlds most populous city from around 1831 to 1925, Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Pauls Cathedral, Tower Bridge, Trafalgar Square, and The Shard. The London Underground is the oldest underground railway network in the world, the etymology of London is uncertain. It is an ancient name, found in sources from the 2nd century and it is recorded c.121 as Londinium, which points to Romano-British origin, and hand-written Roman tablets recovered in the city originating from AD 65/70-80 include the word Londinio. The earliest attempted explanation, now disregarded, is attributed to Geoffrey of Monmouth in Historia Regum Britanniae and this had it that the name originated from a supposed King Lud, who had allegedly taken over the city and named it Kaerlud. From 1898, it was accepted that the name was of Celtic origin and meant place belonging to a man called *Londinos. The ultimate difficulty lies in reconciling the Latin form Londinium with the modern Welsh Llundain, which should demand a form *lōndinion, from earlier *loundiniom. The possibility cannot be ruled out that the Welsh name was borrowed back in from English at a later date, and thus cannot be used as a basis from which to reconstruct the original name. Until 1889, the name London officially applied only to the City of London, two recent discoveries indicate probable very early settlements near the Thames in the London area

Mickey Mouse
–
Mickey Mouse is a funny animal cartoon character and the official mascot of The Walt Disney Company. He was created by Walt Disney and Ub Iwerks at the Walt Disney Studios in 1928, an anthropomorphic mouse who typically wears red shorts, large yellow shoes, and white gloves, Mickey has become one of the worlds most recognizable characters. Mickey first was seen in a single test screening, Mickey officially debuted in the short film Steamboat Willie, one of the first sound cartoons. He went on to appear in over 130 films, including The Band Concert, Brave Little Tailor, Mickey appeared primarily in short films, but also occasionally in feature-length films. Ten of Mickeys cartoons were nominated for the Academy Award for Best Animated Short Film, one of which, Lend a Paw, in 1978, Mickey became the first cartoon character to have a star on the Hollywood Walk of Fame. Beginning in 1930, Mickey has also featured extensively as a comic strip character. His self-titled newspaper strip, drawn primarily by Floyd Gottfredson, ran for 45 years. Mickey has also appeared in books such as Disney Italys Topolino, MM Mickey Mouse Mystery Magazine, and Wizards of Mickey. He also appears in other such as video games as well as merchandising and is a meetable character at the Disney parks. Mickey generally appears alongside his girlfriend Minnie Mouse, his pet dog Pluto, his friends Donald Duck and Goofy, though originally characterized as a mischievous antihero, Mickey was rebranded over time as an everyman, usually seen as a flawed, but adventurous hero. I only hope that we never lose sight of one thing – that it was all started by a mouse, in the spring of 1928, with the series going strong, Disney asked Mintz for an increase in the budget. Angrily, Disney refused the deal and returned to produce the final Oswald cartoons he contractually owed Mintz, Disney was dismayed at the betrayal by his staff but determined to restart from scratch. The new Disney Studio initially consisted of animator Ub Iwerks and an apprentice artist, Les Clark. One lesson Disney learned from the experience was to always make sure that he owned all rights to the characters produced by his company. In the spring of 1928, Disney asked Ub Iwerks to start drawing up new character ideas, Iwerks tried sketches of various animals, such as dogs and cats, but none of these appealed to Disney. A female cow and male horse were also rejected and they would later turn up as Clarabelle Cow and Horace Horsecollar. A male frog was also rejected and it would later show up in Iwerks own Flip the Frog series. Walt Disney got the inspiration for Mickey Mouse from a mouse at his desk at Laugh-O-Gram Studio in Kansas City

Computer History Museum
–
The Computer History Museum is a museum established in 1996 in Mountain View, California, US. The Museum is dedicated to preserving and presenting the stories and artifacts of the information age, the museums origins date to 1968 when Gordon Bell began a quest for a historical collection and, at that same time, others were looking to preserve the Whirlwind computer. The resulting Museum Project had its first exhibit in 1975, located in a coat closet in a DEC lobby. In 1978, the museum, now The Digital Computer Museum, moved to a larger DEC lobby in Marlborough, maurice Wilkes presented the first lecture at TDCM in 1979 – the presentation of such lectures has continued to the present time. TDCM incorporated as The Computer Museum in 1982, in 1984, TCM moved to Boston, locating on Museum Wharf. In 1996/1997, The TCM History Center in Silicon Valley was established, a site at Moffett Field was provided by NASA, in 1999, TCMHC incorporated and TCM ceased operation, shipping its remaining artifacts to TCMHC in 2000. The name TCM had been retained by the Boston Museum of Science so, in 2000, in 2003, CHM opened its new building, at 1401 N. Shoreline Blvd in Mountain View, California, to the public. The facility was heavily renovated and underwent a two-year $19 million makeover before reopening on January 2011. The Computer History Museum claims to house the largest and most significant collection of computing artifacts in the world, the collection comprises nearly 90,000 objects, photographs and films, as well as 4,000 feet of cataloged documentation and several hundred gigabytes of software. The CHM oral history program conducts video interviews around the history of computing and networking, the museums 25, 000-square-foot exhibit Revolution, The First 2000 Years of Computing, opened to the public on January 13,2011. It covers the history of computing in 20 galleries, from the abacus to the Internet, the entire exhibition is also available online. The museum features a Liquid Galaxy in the “Going Places, A History of Silicon Valley” exhibit, the exhibit features 20 preselected locations that visitors can fly to on the Liquid Galaxy. An operating Difference Engine designed by Charles Babbage in the 1840s and it had been on loan since 2008 from its owner, Nathan Myhrvold, a former Microsoft executive. Former media executive John Hollar was appointed CEO of The Computer History Museum in July 2008, in 2012 the APL programming language followed. In February 2013 Adobe Systems, Inc. donated the Photoshop 1.0.1 source code to the collection, on October 21,2014, Xerox Altos source code and other resources followed.

History of the Internet
–
The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of packet networking originated in several science laboratories in the United States, United Kingdom. The US Department of Defense awarded contracts as early as the 1960s for packet network systems, including the development of the ARPANET. Packet switching networks such as ARPANET, NPL network, CYCLADES, Merit Network, Tymnet, Donald Davies first designed a packet-switched network at the National Physics Laboratory in the UK, which became a testbed for UK research for almost two decades. The ARPANET project led to the development of protocols for internetworking, Access to the ARPANET was expanded in 1981 when the National Science Foundation funded the Computer Science Network. In 1982, the Internet protocol suite was introduced as the networking protocol on the ARPANET. Commercial Internet service providers began to emerge in the very late 1980s, the ARPANET was decommissioned in 1990. The research and education community continues to develop and use advanced networks such as NSFs very high speed Backbone Network Service, Internet2, increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. Today the Internet continues to grow, driven by ever greater amounts of information, commerce, entertainment. Such communication systems were limited to point to point communication between two end devices. Telegraph systems and telex machines can be considered precursors of this kind of communication. The Telegraph in the late 19th century was the first fully digital communication system, fundamental theoretical work in data transmission and information theory was developed by Claude Shannon, Harry Nyquist, and Ralph Hartley in the early 20th century. Early computers had a processing unit and remote terminals. As the technology evolved, new systems were devised to allow communication over longer distances or with higher speed that were necessary for the computer model. These technologies made it possible to exchange data between remote computers, however, the point-to-point communication model was limited, as it did not allow for direct communication between any two arbitrary systems, a physical link was necessary. The technology was considered unsafe for strategic and military use because there were no alternative paths for the communication in case of an enemy attack. With limited exceptions, the earliest computers were connected directly to terminals used by individual users, such networks became known as local-area networks. Networking beyond this scope, known as wide-area networks, emerged during the 1950s, J. C. R. Licklider, Vice President at Bolt Beranek and Newman, Inc

DARPA
–
The Defense Advanced Research Projects Agency is an agency of the U. S. Department of Defense responsible for the development of emerging technologies for use by the military. DARPA was created in February 1958 as the Advanced Research Projects Agency by President Dwight D. Eisenhower and its purpose was to formulate and execute research and development projects to expand the frontiers of technology and science, with the aim to reach beyond immediate military requirements. DARPA was created in response to the Soviet launching of Sputnik 1 in 1957, the name of the organization changed several times from its founding name ARPA, DARPA, ARPA, and DARPA. DARPA is independent from other research and development and reports directly to senior Department of Defense management. DARPA has about 240 employees, of whom 13 are in management, dARPA-funded projects have provided significant technologies that influenced many non-military fields, such as computer networking and graphical user interfaces in information technology. S. The mission statement has evolved over time, today, DARPAs mission is still to prevent technological surprise to the U. S. but also to create technological surprise for U. S. enemies. The creation of the Advanced Research Projects Agency was authorized by President Dwight D.15 and its creation was directly attributed to the launching of Sputnik and to U. S. realization that the Soviet Union had developed the capacity to rapidly exploit military technology. Initial funding of ARPA was $520 million, ARPAs first director, Roy Johnson, left a $160,000 management job at General Electric for an $18,000 job at ARPA. Herbert York from Lawrence Livermore National Laboratory was hired as his scientific assistant, Johnson and York were both keen on space projects, but when NASA was established later in 1958 all space projects and most of ARPAs funding were transferred to it. Johnson resigned and ARPA was repurposed to do high-risk, high-gain, far out basic research, ARPAs second director was Brigadier General Austin W. Betts, who resigned in early 1961. He was succeeded by Jack Ruina who served until 1963, Ruina, the first scientist to administer ARPA, managed to raise its budget to $250 million. In pursuit of this mission, DARPA has developed and transferred technology programs encompassing a range of scientific disciplines that address the full spectrum of national security needs. From 1958 to 1965, ARPAs emphasis centered on major issues, including space, ballistic missile defense. During 1960, all of its civilian space programs were transferred to the National Aeronautics and Space Administration and the military space programs to the individual Services. This allowed ARPA to concentrate its efforts on the Project Defender, Project Vela, and Project AGILE Programs, and to work on computer processing, behavioral sciences. The DEFENDER and AGILE Programs formed the foundation of DARPA sensor, surveillance, and directed energy R&D, particularly in the study of radar, infrared sensing, ARPA at this point played an early role in Transit a predecessor to the Global Positioning System. Fast-forward to 1959 when a joint effort between DARPA and the Johns Hopkins Applied Physics Laboratory began to fine-tune the early explorers’ discoveries, TRANSIT, sponsored by the Navy and developed under the leadership of Dr. Richard Kirschner at Johns Hopkins, was the first satellite positioning system. The agency was renamed the Defense Advanced Research Projects Agency in 1972, and during the early 1970s, it emphasized direct energy programs, information processing, concerning information processing, DARPA made great progress, initially through its support of the development of time-sharing

Internet protocol suite
–
The Internet protocol suite is the conceptual model and set of communications protocols used on the Internet and similar computer networks. It is commonly known as TCP/IP because the protocols in the suite are the Transmission Control Protocol. It is occasionally known as the Department of Defense model, because the development of the model was funded by DARPA. The Internet protocol suite provides end-to-end data communication specifying how data should be packetized, addressed, transmitted, routed and received and this functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved. Technical standards specifying the Internet protocol suite and many of its constituent protocols are maintained by the Internet Engineering Task Force, the Internet protocol suite model is a simpler model developed prior to the OSI model. The Internet protocol suite resulted from research and development conducted by the Defense Advanced Research Projects Agency in the late 1960s, after initiating the pioneering ARPANET in 1969, DARPA started work on a number of other data transmission technologies. In 1972, Robert E. Cerf credits Hubert Zimmermann and Louis Pouzin, designer of the CYCLADES network, the protocol was implemented as the Transmission Control Program, first published in 1974. Initially, the TCP managed both datagram transmissions and routing, but as the protocol grew, other researchers recommended a division of functionality into protocol layers, postel stated, “we are screwing up in our design of Internet protocols by violating the principle of layering”. Encapsulation of different mechanisms was intended to create an environment where the layers could access only what was needed from the lower layers. A monolithic design would be inflexible and lead to scalability issues, the Transmission Control Program was split into two distinct protocols, the Transmission Control Protocol and the Internet Protocol. The new suite replaced all protocols used previously and this design is known as the end-to-end principle. Using this design, it possible to connect almost any network to the ARPANET, irrespective of the local characteristics. One popular expression is that TCP/IP, the product of Cerf and Kahns work. A computer called a router is provided with an interface to each network and it forwards packets back and forth between them. Originally a router was called gateway, but the term was changed to avoid confusion with other types of gateways, from 1973 to 1974, Cerfs networking research group at Stanford worked out details of the idea, resulting in the first TCP specification. A significant technical influence was the early networking work at Xerox PARC, DARPA then contracted with BBN Technologies, Stanford University, and the University College London to develop operational versions of the protocol on different hardware platforms. Four versions were developed, TCP v1, TCP v2, TCP v3 and IP v3, the last protocol is still in use today. In 1975, a two-network TCP/IP communications test was performed between Stanford and University College London, in November,1977, a three-network TCP/IP test was conducted between sites in the US, the UK, and Norway
