What kind of machine did Herman Hollerith develop?

Herman Hollerith developed the tabulating machine, which was designed to automate the process of tabulating data, particularly for the purposes of the 1890 U.S. Census. This machine utilized punched cards to store and process information, significantly decreasing the time required to compile census data compared to manual methods. The innovation was crucial in demonstrating how machines could handle large amounts of data efficiently, paving the way for future developments in data processing and computing.

While other terms like calculation device, data analyzer, and computing engine may describe various types of machines found in computing history, they do not accurately represent Hollerith's specific contribution. The terms may refer to broader categories of machines that perform specific functions rather than the particular invention of the tabulating machine, which is uniquely characterized by its use of punched cards for tabulation.
