History of Computing - Pre Historic Era 100.000 bc - 1438 bc

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. In this and the following chapters the same sort of events will occur in different time epochs.

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.

History of IBM

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. Chronology[edit] 1880s–1924: The origin of IBM[edit] Tabulating Machine Company plant in 1893. The roots of IBM date back to the 1880s, decades before the development of electronic computers. Based in New York City, the new company had 1,300 employees and offices and plants in Endicott and Binghamton, New York; Dayton, Ohio; Detroit, Michigan; Washington, D.C.; and Toronto, Ontario.

100 - Welcome to IBM100. Archives: History of IBM. The character of a company -- the stamp it puts on its products, services and the marketplace -- is shaped and defined over time.

Archives: History of IBM

It evolves. It deepens. It is expressed in an ever-changing corporate culture, in transformational strategies, and in new and compelling offerings for customers. IBM's character has been formed over nearly 100 years of doing business in the field of information-handling. Nearly all of the company's products were designed and developed to record, process, communicate, store and retrieve information -- from its first scales, tabulators and clocks to today's powerful computers and vast global networks.

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.

Alan Turing Scrapbook - Who invented the computer?

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. But the Colossus was crucial in showing Alan Turing the speed and reliability of electronics. Computers: History. Computer Languages History. History of the Laptop Computer. History of computing hardware. The History of computing hardware covers the developments from simple devices to aid calculation, to mechanical calculators, punched card data processing and on to modern stored-program computers.

History of computing hardware

Before the 20th century, most calculations were done by humans. Early mechanical tools to help humans with digital calculations were called "calculating machines", by proprietary names, or even as they are now, calculators. The machine operator was called the computer. The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic operation, then manipulate the device to obtain the result. The slide rule and, later, analog computers represented numbers in a continuous form, for instance distance along a scale, rotation of a shaft, or a voltage.
