Understanding how a computer processes data helps users move beyond surface-level interaction and gain insight into how digital systems actually work. At its foundation, data processing is not complex or mysterious. Every computer, from a smartphone to a large server, follows the same logical flow to transform raw input into useful output. This process forms the backbone of all modern computing. The Fundamental Data Processing Cycle All computing systems operate using a continuous cycle: Input → Processing → Output → Storage This cycle repeats endlessly while a system is running. Each stage plays a distinct role, and removing any one of them would break the entire process. Input repre...
