Computer's history

  • The Colossus

    The Colossus
    Tommy Flowers created the Colossus computer during WWII to decrypt encrypted signals from the German teleprinter Lorenz cipher, and it is regarded as one of the first programmable digital computers. At the time, the Colossus machines were top-secret, and their existence was not generally acknowledged until decades later.

    1st Generation of Computers

    The First Generation of Computers lasted from 1946 to 1959 and it was characterised by the vacuum tubes, which were used during the first generation of computers.

    On February 14, 1946, ENIAC (Eletronic Numerical Interpreter and Calculator) was born, also known by its translation into Spanish as “Electronic Numerical Integrator and Computer.”

    The Electronic Delay Storage Automatic Calculator (EDSAC), built at the University of Cambridge in the United Kingdom, ran its initial programs in 1949. It was the first regularly used stored-program computer.

    UNIVAC I was the world’s 1st commercially electronic computing device. It absolutely was created by Eckert and Mauchly in 1947. This milestone marks the transition from experimental machines to practical computing devices.
  • IBM-701

    On April 29, 1952, firm president Thomas J. Watson Jr. notified the owners of the development of what would be "the most advanced, most flexible, and fastest computer in the world," the IBM 701, also known as the Defense Calculator.
  • IBM-650

    The IBM 650 was one of the earliest large-scale computers produced. It was announced in 1953, and 2,000 units were manufactured between 1954 (first sale) and 1962. It is a magnetic roller-based data processing system.

    The 2nd generation of computers

    The second generation of computers lasted from 1959 to 1965 when the vacuum tubes of the first generation were replaced by transistors.
  • IBM-1620

    The IBM-1620 was announced on October 21st, 1959 as one of the "economic scientific equipment" widely used in universities and training centrers.
  • CDC 1604

    CDC 1604
    Seymour Cray, who went on to design supercomputers, and his team at the Control Data Corporation (CDC), created the 1604 as the most powerful computer of its day. Real-time data processing, weapon system control, large-scale scientific problem solving, and commercial applications were all possible with the CDC 1604.
  • IBM 7094

    IBM 7094
    On January 15, 1962, IBM unveiled the 7094 computer, which was designed to be utilized in scientific-technological applications that demanded high computational capability at the time.
  • CDC 3600

    CDC 3600
    The CDC 3600 had 32,700 48-bit words of magnetic core memory and was capable of running FORTRAN. The CDC 3600 was praised for its smoked glass panels and "solid and stunning" design. Seymour Cray has done much of the basic architecture design work on the CDC 3000 series systems.
  • UNIVAC 1108

    UNIVAC 1108
    J. Presper Eckert and John William Mauchly were the primary designers. It was part of the UNIVAC 1100 series of computers starting in 1964, when thin film memory was replaced with integrated circuits and smaller and faster cores were utilized for memory.

    3rd generation of computers

    The third generation of computers lasted from 1964-1971 and it is characterized by the incorporation of integrated circuits that replaced transistors. Integrated circuits are silicon chips of a few square millimeters with various components that construct a miniature electronic circuit and are covered in a plastic/ceramic encapsulation.
  • Pascal programming language

    Pascal programming language
    Apart from COBOL and FORTRAN programming languages taht appeared in the second generation of computers, Pascal, another computer programming language developed by Niklaus Wirth of Switzerland, appeared in 1970 to teach systematic programming. It emphasizes the use of conditional and loop control structures in an organized manner without the use of GOTO instructions.
  • IBM System/370

    IBM System/370
    IBM introduces the IBM System/360, a line of mainframe computers that are model-to-model compatible. This standardized architecture creates a new industry standard and is essential for computer adoption.
  • Intel 4004

    Intel 4004
    The Intel 4004 was the world's first microprocessor, a 4-bit CPU placed in a 16-pin chip with 2,300 transistors.

    The 4th generation of computers

    The 4th gen lasted from 1971-1980. Fourth generation computers employed VLSI circuits that enabled the development of 4th generation microcomputers. Computers of the 4th generation were increasingly powerful, compact, reliable and economical. As a result, the Personal Computer (PC) revolution was born. Time sharing, real-time networks and distributed operating systems were used. This generation makes use of all high-level languages such as C, C++, DBASE, and so on.
  • VLSI (Very Large Scale Integrated circuit)

    VLSI (Very Large Scale Integrated circuit)
    It is a technology that enables the integration of hundreds or even millions of transistors onto a single silicon chip. This is accomplished by employing modern manufacturing techniques that allow component sizes to be compressed to the nanoscale scale.
  • Apple II

    Apple II
    In 1976, Steve Jobs and Steve Wozniak released the first microcomputer known as Apple II. It features a color display, a keyboard, and expansion slots, making it accessible to a broader audience.
  • First Atari console

    First Atari console
    The Atari 2600 is a video game console that was released in September 1977 under the name Atari VCS (Video Computer System), becoming the first video game system to achieve widespread success and popularizing interchangeable cartridges.

    The 5th generation of computers

    The fith generation of computers is from 1980 till the present and it is characterized by more advanced microporcessors, the development of artifitial intelligence, advanced robotics...
  • RISC (Reduced instruction set computer)

    RISC (Reduced instruction set computer)
    For battery-powered devices where energy efficiency is critical, RISC gives great performance per watt. A RISC processor performs only one action per instruction. The operation execution time is reduced by completing it in a single cycle.
