MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -Herman Hollerith’s tabulator consisted of electrically-operated components that captured and processed census data by “reading” holes on paper punch cards .

Detailed explanation-2: -It was successful, and Hollerith went on to found the Tabulating Machine Company, which later merged to become a company called IBM. Although tabulating machines are an early part of computer history, realize they are not considered computers. These machines only tabulated (counted), they were not programmable.

Detailed explanation-3: -The machine used a system of electrical and mechanical signals, and a set of wires positioned over pools of mercury, to incrementally count data on paper punch cards. A Hollerith machine is also known as a tabulating machine or Hollerith tabulator.

Detailed explanation-4: -Herman Hollerith’s punched card tabulator transformed the census process-and information processing in general-beginning with the 1890 US census. The machine was able to collect and count data more rapidly and accurately than manual processes had allowed in the past.

Detailed explanation-5: -His invention of the punched card machine marked the beginning of the automatic data processing age. Whereas punched cards had previously been used to control looms, Hollerith now used them to store data.
