A small introduction to this timeline. Centuries ago knowledge traveled with caravans between India to an area what we now call Middle East and back. It were mathematicians (called philosophers) that traveled along and passed the knowledge to people at their destination. Sometimes they were even invited to come over and amuse a king or other rulers in Mesopotamia, Turkey, Egypt, India and China. The same thing happened at courts in Europe, centuries later. Mostly they stayed several years at a king's court and it was no exception that they changed courts from one king to another thousands of miles away.
International Business Machines , abbreviated IBM and nicknamed "Big Blue", is a multinational computer technology and IT consulting corporation headquartered in Armonk, New York , United States. The company is one of the few information technology companies with a continuous history dating back to the 19th century. IBM manufactures and sells computer hardware and software (with a focus on the latter), and offers infrastructure services, hosting services, and consulting services in areas ranging from mainframe computers to nanotechnology . [ 1 ] Ginni Rometty is the president and CEO of IBM.
Want to know who the self-confessed "mother of the motherboard" is? Or why every piece of organically farmed, tenderly loved food at your local Trader Joe's has a barcode on it? Or perhaps you're curious to learn more about how millions of airline reservations can be made around the world with unfailing reliability?
The character of a company -- the stamp it puts on its products, services and the marketplace -- is shaped and defined over time. It evolves. It deepens.
Even when they turned to electronics, builders of calculators still thought of programs as something quite different from numbers, and stored them in quite a different, inflexible, way. So the ENIAC, started in 1943, was a massive electronic calculating machine, but I would not call it a computer in the modern sense, though some people do. This page shows how it took a square root — incredibly inefficiently. Colossus The Colossus was also started in 1943 at Bletchley Park, heart of the British attack on German ciphers (see this Scrapbook page. ) I wouldn't call it a computer either, though some people do: it was a machine specifically for breaking the "Fish" ciphers, although by 1945 the programming had become very sophisticated and flexible.
Below, you can see the preview of the Computer Languages History (move on the white zone to get a bigger image): If you want to print this timeline, you can freely download one of the following PDF files: There is only 50 languages listed in my chart, if you don't find "your" language, see The Language List of Bill Kinnersley (he has listed more than 2500 languages). Here is the ChangeLog of this history. Note: I have now a page where I explain how I build this chart. <p style="text-align:right;color:#A8A8A8"></p>
Computing hardware evolved from machines that needed separate manual action to perform each arithmetic operation, to punched card machines, and then to stored-program computers . The history of stored-program computers relates first to computer architecture, that is, the organization of the units to perform input and output, to store data and to operate as an integrated mechanism. Before the development of the general-purpose computer, most calculations were done by humans. Mechanical tools to help humans with digital calculations were then called "calculating machines", by proprietary names, or even as they are now, calculators . It was those humans who used the machines who were then called computers.
