The Univac 1 is the first commercial computer to attract widespread public attention. On June 14, 1951 the very first electronic computer produced in series (and in the United States), the UNIVAC I (Universal Automatic Computer) was delivered to the US States Census Bureau at the price of $1.6 Mio. On June 14, 1951, the U.S. Census Bureau dedicates UNIVAC, the world’s first commercially produced electronic digital computer. UNIVAC tapes were ½" wide, 0.0015" thick, up to 1,500' long, and made of phosphor-bronze with a metallic coating. 1975: The January issue of Popular Electronics magazine features the Altair 8080, described as the "world's first minicomputer kit to rival commercial models." Spectra systems were marketed on the basis of their compatibility with the IBM System/360 series of computer since it implemented the IBM 360 instruction set and could run most IBM software with little or no modification. The first Cray-1 supercomputer was installed at Los Alamos National Laboratory in 1972. In 1954 Lyons formed LEO … More than 1,800 of these computers are sold in an eight-year span, with 120 installations in the first year. First delivered to the United States Government in 1950, the UNIVAC 1101 or ERA 1101 is considered to be the first computer that was capable of storing and running a program from memory. 2. Stored-program concept, Storage of instructions in computer memory to enable it to perform a variety of tasks in sequence or intermittently. It took up 15,000 feet, employed 17,000 vacuum tubes, and was programmed by plugging and replugging some 6,000 switches. The UNIVAC was the first commercial computer delivered to a business client, the U.S. Census Bureau in 1951. The first PC clone The first multimedia computer In 1942, Konrad Zuse begin working on the Z4, which later became the first commercial computer after being sold to Eduard Stiefel a mathematician of the Swiss Federal Institute of Technology Zurich on July 12, 1950. 4) MITS Altair in the 1980s. The Z4 is credited as being the first commercial computer after being sold to a Swiss mathematician in 1950. The Bureau purchased a second UNIVAC I machine in the mid-1950's, and two UNIVAC 1105 [JPG] computers for the 1960 census. Find out First commercial computer with a mouse Answers. On June 14, 1951, the U.S. Census Bureau dedicates UNIVAC, the world’s first commercially produced electronic digital computer. Visit again, as this article will be updated regularly, with more useful information about early computers. 31, 1951, the U.S. Census Bureau signed a contract for the first commercial computer in the U.S. and thus entered a new era. The Univac 1 is the first commercial computer to attract widespread public attention. Weighing about three pounds, each reel could hold 1,440,000 decimal digits and could be read at 100 inches/sec. A Xerox commercial from that time featured a … Mathematician Grace Hopper completes A-0, a program that allows a computer user to use English-like words instead of numbers to give the computer instructions. The UNIVAC I was the first general-purpose electronic digital computer design for business application produced in the United States. It had a tiny computer screen built into it. During the Johnson administration, ...read more, On June 14, 1922, President Warren G. Harding, while addressing a crowd at the dedication of a memorial site for the composer of the “Star Spangled Banner,” Francis Scott Key, becomes the first president to have his voice transmitted by radio. In the 1980s, the development of the microprocessor made possible small, powerful computers such as the personal computer, and more recently the laptop and hand-held computers. Each core stored a bit, magnetized one way for a “zero,” and the other way for a “one.” The wires could both detect and change the state of a bit. Created by Presper Eckert and John Mauchly -- designers of the earlier ENIAC computer -- the Univac 1 used 5,200 vacuum tubes and weighed 29,000 pounds. Though nominally controlled by Mexico, California was home ...read more, Harriet Beecher Stowe, author of Uncle Tom’s Cabin, is born on June 14, 1811 in Litchfield, Connecticut, the seventh child of Congregationalist minister Lyman Beecher. Who built LEO—and how? It could read 7,200 decimal digits per second (it did not use binary numbers), making it by far the fastest business machine yet built. The idea was introduced in the late 1940s by John von Neumann, who proposed that a program be electronically stored in binary-number format in a memory device so that instructions could be modified by the computer as determined by … In 1937 the first electronic digital computer was built by Dr. John V. Atanasoff and Clifford Berry. Stowe studied at private schools in Connecticut and worked as a teacher in Hartford for five years until her ...read more, TWA Flight 847 from Athens to Rome is hijacked by Shiite Hezbollah terrorists who immediately demand to know the identity of ”those with Jewish-sounding names.” Two of the Lebanese terrorists, armed with grenades and a 9-mm. Influenced by Atanasoff’s work, Presper Eckert and John Mauchly set about building the first general-purpose electronic digital computer in 1943. First Commercial Computer In 1947, J Lyons and Co, a British company famous for its tea-shops, began work on the Leo computers. What was the name for the first commercial computer produced in the USA which was used for forecasting the 1952 election results? This chapter discusses the first commercial computers including the UNIVAC I developed by EMCC/Sperry in the United States for the US Census Bureau and the LEO I computer developed by J. Lyons and Co. in England in partnership with Maurice Wilkes of Cambridge University.
