👉 Manual computing refers to the practice of performing calculations and data processing using traditional, non-digital methods such as mechanical calculators, slide rules, and analog computers. These tools rely on physical components like gears, levers, and electrical circuits to execute mathematical operations. For instance, mechanical calculators use gears and dials to perform arithmetic functions, while slide rules employ logarithmic scales to facilitate multiplication, division, and other calculations. Analog computers, on the other hand, use continuous signals to model and solve complex problems in fields like engineering and physics. Despite the advent of digital technology, manual computing remains a valuable skill for understanding fundamental mathematical concepts and serves as a backup method in situations where electronic devices may fail. It also fosters a deeper appreciation for the historical development of computational methods and enhances problem-solving abilities in a non-digital context.
