    A human computer, with microscope and calculator, 1952. It was not until the mid-20th century that the word acquired its modern definition; according to the Oxford English Dictionary, the first known use of the word computer was in a different sense, in a 1613 book called The Yong Mans Gleanings by the English writer Richard Brathwait: "I haue [] read the truest computer of Times, and the best ...

    Computer simulation, one of the main cross-computing methodologies. Computing is any goal-oriented activity requiring, benefiting from, or creating computing machinery. [1] It includes the study and experimentation of algorithmic processes, and the development of both hardware and software. Computing has scientific, engineering, mathematical ...

    The first known computer algorithm was written by Ada Lovelace in the 19th century for the Analytical Engine, to translate Luigi Menabrea's work on Bernoulli numbers for machine instruction. [3] However, this remained theoretical only - the lesser state of engineering in the lifetime of these two mathematicians proved insufficient [ citation ...

    This is the Antikythera mechanism, which is considered the first mechanical analog computer, dating back to the first century BC.. Ideas of computer science were first mentioned before the 1950s under the Massachusetts Institute of Technology (MIT) and Harvard University, where they had discussed and began thinking of computer circuits and numerical calculations.

  7. Computational thinking - Wikipedia

    en.wikipedia.org/wiki/Computational_thinking

    The history of computational thinking as a concept dates back at least to the 1950s but most ideas are much older. [6] [3] Computational thinking involves ideas like abstraction, data representation, and logically organizing data, which are also prevalent in other kinds of thinking, such as scientific thinking, engineering thinking, systems thinking, design thinking, model-based thinking, and ...

    The MITS Altair, the first commercially successful microprocessor kit, was featured on the cover of Popular Electronics magazine in January 1975. It was the world's first mass-produced personal computer kit, as well as the first computer to use an Intel 8080 processor. It was a commercial success with 10,000 Altairs being shipped.

    1974 saw the introduction of what is considered by many to be the first true personal computer, the Altair 8800 created by Micro Instrumentation and Telemetry Systems (MITS). [ 24 ] [ 25 ] Based on the 8-bit Intel 8080 Microprocessor, [ 26 ] the Altair is widely recognized as the spark that ignited the microcomputer revolution [ 27 ] as the ...
