What are the main features of mechanical data processing?

Mechanical data processing involves the use of physical devices and machines to manipulate and analyze data. Key features include the use of mechanical components like gears and levers for calculations, the ability to perform repetitive tasks efficiently, and limited programmability compared to electronic systems. It typically requires manual input and oversight, and its speed and accuracy are constrained by the mechanical nature of the devices used. Overall, mechanical data processing laid the foundation for more advanced electronic data processing technologies.
