Timeline about history of computers

  • 825 BCE

    Abu Ja'far Mohammed ibn Musa al-Khowarizmi

    Abu Ja'far Mohammed ibn Musa al-Khowarizmi
    He discovered the algorithms.
  • 450 BCE

    Ancient Greece

    Ancient Greece
    They made an enormous contribution to the systematization of reasoning. The formal principles of mathematics were developed in Greece. This period is known as the classical period.
  • 500

    Hindus

    Hindus
    he decimal numbering of position we use comes from the Hindu numbering system who invented zero.
  • 1202

    Leonardo Fibonacci

    Leonardo Fibonacci
    He was the first to write about Arabic numerals in the West.He had the opportunity to travel extensively through North Africa. There he learned Arabic numbering and positional notation with zero. He also wrote a book that served to introduce Arabic numerals into Europe.
  • 1580

    Francois Viéte

    Francois Viéte
    He began to use letters to symbolize unknown values and thus laid the foundations of algebra.
  • John Napier

    John Napier
    The one who invented logarithms.
  • Blaise Pascal

    Blaise Pascal
    He is generally regarded as the inventor of the calculator, manufactured his wits twenty years after Schickard and was less advanced.
  • Ada Lovelace

    Ada Lovelace
    She developed the first "programs" for computers and laid the foundations for programming languages.
  • Georges Boole

    Georges Boole
    When he was around sixteen, he learned Latin and Greek on his own, and later learned French, Italian and German. Also self-taught, Boole learned virtually all known mathematics in his time. His most prominent contribution was "An Investigation into the Laws of Truth". He established for the process of reasoning a symbolic representation. To do this he used variables that could only adopt two values "1" (true) and "0" (false), discarding any value of "half truth"
  • Mark 1

    Mark 1
    It was an electromechanical machine capable of multiplying two numbers in six seconds and dividing them by twelve.
  • Eniac

    Eniac
    It was the mother of all computers. The first fully electronic digital computer, it was used it was for general purposes, designed by physicist John V. Atanasoff. It used decimal arithmetic.
  • Assembly languages

    Assembly languages
    The first symbolic languages to programate computers. The first high-level languages were developed such as FORTRAN, COBOL and PASCAL.
  • Fist computer generation

    Fist computer generation
    Computers used vacuum valves to process all the information.The programming was done through machine language. The memories were constructed of thin tubes of liquid mercury and magnetic drums.
  • SPUTNIK

    SPUTNIK
    The first artificial satellite sended to the space by the Soviet Union
  • Second computer generation

    Second computer generation
    Transistor replaces the vacuum tubeused in the first generation. Second-generation computers were faster, smaller, and required less ventilation.
  • Third computer generation

    Third computer generation
    They emerged with the development of integrated circuits in which thousands of electronic components are placed, in a miniature integration.
  • Fourth computer generation

    Fourth computer generation
    Two improvements in computer technology markedthe beginning of the fourth generation: the replacement of memories with magnetic cores by those of silicon chips and the placement of many more components on a Chip: a product of the micro-miniaturization of electronic circuits. The small size of the microprocessor and chips made the creation of Personal Computers possible.
  • Fifth computer generation and artificial intelligence

    Fifth computer generation and artificial intelligence
    Two great technological advances, which serve as parameters for the beginning of this generation: the creation in 1982 of the first supercomputer with parallel processing capacity, and the announcement by the Japanese government of the “Fifth Generation” project, which,according to was established in the agreement with six of the largest Japanese computer companies, it should end in 1992.
  • Sixth computer generation

    Sixth computer generation
    Some of the technological advances of the last decade of the 20th century and what is expected to be achieved in the 21st century are also mentioned. Computers of this generation have combined Parallel / Vectorial architectures, with hundreds of vector microprocessors working at the same time; Computers have been created capable of performing more than a millionofmillions offloating point arithmetic operations per second.
