early computing technology

Early computing technology began with mechanical devices like the abacus and later evolved to machines such as the Analytical Engine, which used gears and levers to perform calculations. The 20th century saw the development of vacuum tube computers, which used electronic components to process data faster. These evolved into stored-program computers with binary systems, enabling complex calculations and programming. Early computers were large, expensive, and used for specialized tasks, laying the foundation for modern digital technology. Over time, advancements like transistors and microprocessors made computers smaller, faster, more affordable, and versatile, transforming how we work and communicate.
