👉 Computing, at its core, refers to the use of machines and software to process information and solve problems. Before modern computers, humans relied on physical tools like abacuses, calculators, and manual calculations to perform computations. The advent of electronic computers in the mid-20th century revolutionized this process by automating calculations and handling vast amounts of data with unprecedented speed and accuracy. Early computers used vacuum tubes and later transistors to store and process binary data (0s and 1s), laying the foundation for today's digital computing systems. These machines could perform repetitive tasks much faster than humans, enabling advancements in fields such as science, engineering, finance, and communication. The evolution from mechanical calculators to complex supercomputers has transformed computing into an indispensable tool for modern society, driving innovation and efficiency across numerous industries.
