Evolution of computing devices

Explore the evolution of early computing devices that laid the foundation for modern technology. Starting with the Abacus, developed in China around 3000 BC, and moving through the Pascaline, invented by Blaise Pascal between 1642 and 1644 which could perform basic arithmetic, to the Leibnitz Calculator created by Gottfried Wilhelm Leibnitz in 1671 that could add, subtract, multiply, divide, and even extract square roots. Discover these pivotal inventions that shaped the journey of computation.
