In computer history, the most important initial calculation tool was abacus. And it was widely used for over 2,000 years. Two other computing tools, Astrolabe, were also used for navigation about 2000 years ago. Blaise Pascal manufactured the first "digital computing machine" in 1642 and was widely acknowledged. It is designed to help the father who is the tax collector of Pascal who can enter the number just by dialing. In 1671, Gottfried Wilhelm von Leibniz invented a computer built in 1694; it can be added and multiplied by continuous additions and shifts.
However, it turned out that this also applies to the history of computer science. As you start exploring the chronology of various structures, algorithms, and concepts in history, you will find that recent discoveries and creations are adjustments and adjustments to the structures you have already learned. Well, I am not a historian, but I concluded that even the latest "invention" in the field of computer and computer science "invented" existing concepts. In other words, they are ideas built with smaller parts, these ideas are tethered and built on the idea previously created by others in that field.
Computer history Computes the myth of linear progress. Calculation history is rarely required for ideas and inspiration. Computational historical emergencies, competitive vision, and decision making processes are not widely known. To understand computer promises and pitfalls over the years and to avoid duplication and mistakes in future work, students need to learn the history of that field. Alternative Embodiment of Calculation. Today, computing is often embodied in a multipurpose silicon microprocessor, but it is not always the case and it is always true that it is naive. Antikythera mechanism, tide predictor, Norden bomb, long score and nomogram, classic Honeywell thermostat is calculated in clockwork, pen (or ruler) and paper and human, and bimetallic strip. Future calculations will be quantitative, optical or biological.
