The evolution of computers<\/strong> has a long history, starting not with silicon and electronics, but more than 2,500 years ago with devices that were considered high-performance technology at the time, allowing mathematical calculations beyond the capabilities of the human mind.<\/p>\n

Here is a list of the earliest devices.<\/p>\n

The Evolution of Computers<\/h2>\n

    The first calculating device was the abacus, created around 1100 B.C. and still in use today, particularly in Asia.<\/h3>\n

    In 1623, the German astronomer and mathematician Wilhelm Schickard<\/strong><\/em> built the first known calculator<\/strong><\/em>. It was described in a letter to his astronomer friend Johannes Kepler<\/strong><\/em>. Thanks to that letter, the invention’s record was preserved, as it was lost in a fire.

    By 1642, the Pascaline<\/em><\/strong>, the first machine for adding and subtracting that was mass-produced and used by many people, was created. It was designed and built by the French mathematician and philosopher Blaise Pascal<\/em><\/strong>.

    In 1673, based on the Pascaline, the German mathematician and philosopher Gottfried Wilhelm von Leibniz designed this machine called the Stepped Reckoner<\/em> or Leibniz<\/strong> Machine<\/em>. It could add and subtract and also multiply by repeated addition and shifting..

    In 1801, the Jacquard loom was invented, a marvel of the Industrial Revolution. It can be considered the first practical information processing device. It wove patterns into fabric, allowing even the most inexperienced users to create complex designs.

    In 1832, Charles Babbage<\/em> created the Difference Engine<\/em>, an advanced calculator intended to produce logarithmic tables used in navigation. This is famous because Ada Lovelace<\/em> fell in love with its possibilities and ended up creating the first programming language.

    By 1890, Herman Hollerith invented this machine to conduct the U.S. Census. It was called the Census Tabulator.

    In 1930, an engineer named Vannevar Bush invented this analog calculator called the Differential Analyzer<\/em>, which was used to solve differential equations, a common problem in physics and engineering applications that is often very tedious to solve.<\/h3>\n

    In 1946, the ENIAC<\/strong>, an acronym for Electronic Numerical Integrato<\/em>r And Computer<\/em>, the first general-purpose computer, was developed. It was invented by John Presper Eckert and John William Mauchly, with six women contributing to its creation: Betty Snyder Holberton, Jean Jennings Bartik, Kathleen McNulty Mauchly Antonelli, Marlyn Wescoff Meltzer, Ruth Lichterman Teitelbaum, and Frances Bilas Spence.<\/h3>\n
