History of computers

  • Charles Babbage

    Charles Babbage
    A difference engine is an automatic, mechanical calculator designed to tabulate polynomial functions. The name derives from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial coefficients. Both logarithmic and trigonometric functions, functions commonly used by both navigators and scientists, can be approximated by polynomials, so a difference engine can compute many useful sets of numbers.

    Floppy Disc- Stugart
    In 1976, Shugart Associates introduced the first 5 1⁄4-inch FDD. By 1978 there were more than 10 manufacturers producing such FDDs. There were competing floppy disk formats, with hard and soft sector versions and encoding schemes such as FM, MFM and GCR. The 5 1/4 inch format displaced the 8-inch one for most applications, and the hard sectored disk format disappeared. In 1984, IBM introduced the 1.2 MB dual sided floppy disk along with its AT model. IBM started using the 720 kB

    CD-ROM- Phillips
    It all started in the year 1979, when Philips and Sony got together to design a new digital audio disc. The team leaders of this project were Kees Immink and Toshitada Doi. Philps handled the maunfacturing process along with the Eight-to-Fourteen Modulation (EFM), while Sony too care of the error connection method, better known as CIRC. However, Philips claim that this invention was not a one man's job but a collective contribution by members of both the companies who worked together as a team.

    Windows 3.0 (1990) and Windows 3.1 (1992) improved the design, mostly because of virtual memory and loadable virtual device drivers (VxDs) that allowed them to share arbitrary devices between multitasked DOS windows.[citation needed] Also, Windows applications could now run in protected mode (when Windows was running in Standard or 386 Enhanced Mode), which gave them access to several megabytes of memory and removed the obligation to participate in the software virtual memory scheme
