Bolt Beranek And Newman
Raytheon BBN (originally Bolt Beranek and Newman Inc.) is an American research and development company, based next to Fresh Pond in Cambridge, Massachusetts, United States. In 1966, the Franklin Institute awarded the firm the Frank P. Brown Medal, in 1999 BBN received the IEEE Corporate Innovation Recognition, and on 1 February 2013, BBN was awarded the National Medal of Technology and Innovation, the highest honors that the U.S. government bestows upon scientists, engineers and inventors, by President Barack Obama. It became a wholly owned subsidiary of Raytheon in 2009. History BBN has its roots in an initial partnership formed on 15 October 1948 between Leo Beranek and Richard Bolt, professors at the Massachusetts Institute of Technology. Bolt had won a commission to be an acoustic consultant for the new United Nations permanent headquarters to be built in New York City. Realizing the magnitude of the project at hand, Bolt had pulled in his MIT colleague Beranek for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subsidiary
A subsidiary, subsidiary company or daughter company is a company owned or controlled by another company, which is called the parent company or holding company. Two or more subsidiaries that either belong to the same parent company or having a same management being substantially controlled by same entity/group are called sister companies. The subsidiary can be a company (usually with limited liability) and may be a government- or state-owned enterprise. They are a common feature of modern business life, and most multinational corporations organize their operations in this way. Examples of holding companies are Berkshire Hathaway, Jefferies Financial Group, The Walt Disney Company, Warner Bros. Discovery, or Citigroup; as well as more focused companies such as IBM, Xerox, and Microsoft. These, and others, organize their businesses into national and functional subsidiaries, often with multiple levels of subsidiaries. Details Subsidiaries are separate, distinct legal entities f ...

LGP-30
The LGP-30, standing for Librascope General Purpose and then Librascope General Precision, was an early off-the-shelf computer. It was manufactured by the Librascope company of Glendale, California (a division of General Precision Inc.), and sold and serviced by the Royal Precision Electronic Computer Company, a joint venture with the Royal McBee division of the Royal Typewriter Company. The LGP-30 was first manufactured in 1956, at a retail price of $47,000, . The LGP-30 was commonly referred to as a desk computer. Its height, width, and depth, excluding the typewriter shelf, was . It weighed about , and was mounted on sturdy casters which facilitated moving the unit. Design The primary design consultant for the Librascope computer was Stan Frankel, a Manhattan Project veteran and one of the first programmers of ENIAC. He designed a usable computer with a minimal amount of hardware. The single address instruction set had only 16 commands. Magnetic drum memory held the m ...

Fresh Pond (Cambridge, Massachusetts)
Fresh Pond is a reservoir and park in Cambridge, Massachusetts. Prior to the Pond's use exclusively as a reservoir, its ice had been harvested by Boston's "Ice King", Frederic Tudor, and others, for shipment to North American cities and to tropical areas around the world.Weightman, Gavin, ''The Frozen-Water Trade: A True Story'', New York, Hyperion, 2003. Fresh Pond is bordered by Fresh Pond Parkway, Huron Avenue, Grove Street, Blanchard Road, and Concord Avenue. Fresh Pond Reservation consists of a 155-acre (627,000 m²) kettle hole lake, and 162 acres (656,000 m²) of surrounding land, with a 2.25 mile (3.6 km) perimeter road popular with walkers, runners and cyclists, and a nine-hole golf course. Part of the Watertown–Cambridge Greenway, a rail trail on the alignment of the former Watertown Branch Railroad, runs along the east side of the pond. Early history Native Americans used the pond for fishing and drinking water for several thousand years. Starting in the sevente ...

Frank Heart
Frank Evans Heart (May 15, 1929 – June 24, 2018) was an American computer engineer influential in computer networking. After nearly 15 years working for MIT Lincoln Laboratory, Heart worked for Bolt, Beranek and Newman from 1966 to 1994, during which he led a team that designed the first routing computer for the ARPANET, the predecessor to the Internet. Background Born to a Jewish family in The Bronx, New York City, Heart grew up in Yonkers. His father was an engineer at the Otis Elevator Company; his mother was an insurance agent. Entering as an electrical engineering major, Heart enrolled at the Massachusetts Institute of Technology (MIT) in 1947, entering a five-year master's degree program which he alternated semesters between work and school. During one summer, he worked as a power transformer tester at a General Electric factory. In 1951, he enrolled in MIT's new computer programming course taught by Gordon Welchman. Taking the course led Heart to complete his undergradua ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MIT Lincoln Laboratory
The MIT Lincoln Laboratory, located in Lexington, Massachusetts, is a United States Department of Defense federally funded research and development center chartered to apply advanced technology to problems of national security. Research and development activities focus on long-term technology development as well as rapid system prototyping and demonstration. Its core competencies are in sensors, integrated sensing, signal processing for information extraction, decision-making support, and communications. These efforts are aligned within ten mission areas. The laboratory also maintains several field sites around the world.

Robert Taylor (computer Scientist)
Robert William Taylor (February 10, 1932 – April 13, 2017), known as Bob Taylor, was an American Internet pioneer, who led teams that made major contributions to the personal computer, and other related technologies. He was director of ARPA's Information Processing Techniques Office from 1965 through 1969, founder and later manager of Xerox PARC's Computer Science Laboratory from 1970 through 1983, and founder and manager of Digital Equipment Corporation's Systems Research Center until 1996. Uniquely, Taylor had no formal academic training or research experience in computer science; Severo Ornstein likened Taylor to a "concert pianist without fingers," a perception reaffirmed by historian Leslie Berlin: "Taylor could hear a faint melody in the distance, but he could not play it himself. He knew whether to move up or down the scale to approximate the sound, he could recognize when a note was wrong, but he needed someone else to make the music." His awards include the Nat ...

BBN Time-Sharing System
The BBN Time-Sharing System was an early time-sharing system created at Bolt, Beranek and Newman (BBN) for the PDP-1 computer. It began operation in September 1962. History J. C. R. Licklider left MIT to become a vice president at Bolt Beranek and Newman in 1957. He learned about time-sharing from Christopher Strachey at a UNESCO-sponsored conference on Information Processing in Paris in June 1959. Digital Equipment Corporation's prototype PDP-1 was ready in November, 1959, and the machine was featured in the November/December issue of ''Datamation'' magazine. BBNer Ed Fredkin saw a prototype system at the Eastern Joint Computer Conference in Boston in December 1959, and was extremely interested. Given BBN's interest, DEC's founder and President Ken Olsen visited and explained that DEC had just completed construction of a prototype PDP-1, and that they needed a test site for a month. BBN agreed to be the test site, at its regular hourly rates, and then in early 1960 obtained t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Time-sharing
In computing, time-sharing is the sharing of a computing resource among many users at the same time by means of multiprogramming and multi-tasking.DEC Timesharing (1965), by Peter Clark, The DEC Professional, Volume 1, Number 1 Its emergence as the prominent model of computing in the 1970s represented a major technological shift in the history of computing. By allowing many users to interact concurrently with a single computer, time-sharing dramatically lowered the cost of providing computing capability, made it possible for individuals and organizations to use a computer without owning one, and promoted the interactive use of computers and the development of new interactive applications. History Batch processing The earliest computers were extremely expensive devices, and very slow in comparison to later models. Machines were typically dedicated to a particular set of tasks and operated by control panels, the operator manually entering small programs via switches in order ...
