Detailed explanation-1: -The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.
Detailed explanation-2: -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-3: -The tabulator is shown at the center in the photograph. Hollerith’s tabulating system won a gold medal at the 1889 World’s Fair in Paris, and was used successfully the next year to count the results of the 1890 Census. His inventions formed the starting point of a company that would become IBM.
Detailed explanation-4: -Before Hollerith’s electric tabulating machine, census results were hand-counted and took years to process; the 1880 census results, for example, were not fully processed until 1887.
Detailed explanation-5: -Seaton’s device was first used in 1872, for the 1870 census, and then again in 1880. Seaton also invented a matrix printing apparatus for census work.
