Unformatted text preview: ade, these were followed by one of the major milestone inventions in computing and mathematics; George Boole’s invention of Boolean Algebra. The invention of Boolean Algebra opened up the fields of mathematics, engineering, and computing to the new frontiers in logic in which possibilities are boundless. Sir Charles Wheatstone’s invention of the paper tape to store information in 1857, created new excitement in the computing community of the time. With paper tape, huge amounts of data could be fed into the computing device and similar quantities could be stored. This invention brought computing to a new level and into a new era. From mid 1850 through the turn of the century, computing made broad progress with various inventions including the invention of the Logic Machine by William Stanley Jovons in 1869AD, the invention of the first Keyboard by Sholes around 1874, and the rectangular Logic Diagrams by Allan Marquand in 1881. Starting around 1890, a burst of major inventions similar to those of 1850s started all over again. In 1886, Charles Pierce first linked Boolean Algebra to circuits based on switches, a major break through in mathematics, engineering and computing science. In 1890 John Venn invented the Venn diagrams now used extensively in switching algebras in both hardware and software development. And in 1890, Herman Hollerith invented the Tabulating Machine. Hollerith’s invention utilized Jacquard’s punched card to read the presence or absence of holes. The data read was to be collated using an automatic electrical tabulating machine with large number of clock-like counters that summed up and accumulated the results in a number of selected categories. After 1900 AD After The inventions before 1900AD were all crucial building blocks of the The computing industry. The period created a child but the child did not start blossoming until the second period that started around the turn of the twentieth century. The Century began with a major milestone in the computing history, by the invention of the vacuum tube by John Ambrose Fleming. This was a major development in computing as the vacuum tube played a major role in computing for the next half century. All digital computer in the first half century ran on vacuum tubes. The next twenty years saw development of computing with a variety of inventions including the invention of the triode by Lee de Forest in 1906. 1906. However, another major milestone invention, was to be born during this period. Although it was not to come into full use for some time, but 1926 saw the invention of the first semiconductor transistor that will come to dominate the computing industry in late years. 1937 saw a milestone invention in the history of computing. The invention of the Turing Machine by Alan Turing in 1937 was as revolutionary as it was exciting. Turing, an English mathematician, showed by the invention of an abstract computer, that some problems do not lend themselves to algorithmic representat...
