27 de mar. de 2019 · Hollerith invented and used a punched card device to help analyze the 1890 U.S. census data. His great breakthrough was his use of electricity to read, count and sort punched cards whose holes represented data gathered by the census-takers. His machines were used for the 1890 census and accomplished in one year what would have taken nearly 10 ...

12 de jan. de 2020 · A menudo llamados "el nuevo petróleo", los datos son inmensamente valiosos, pero sólo si se procesan de la forma apropiada, algo que Herman Hollerith hizo en el siglo XIX.
Hollerith’s cards were used for the 1890 US Census, which finished months ahead of schedule and under budget. Punched cards emerged as a core product of what would become IBM more than two decades later. IBM introduced the “IBM Computer Card” in 1928 as the result of a secretive competition between the company’s two top research teams.
A máquina de Hollerith foi utilizada para auxiliar no censo de 1890, reduzindo o tempo de processamento de dados de sete anos, do censo anterior, para apenas dois anos e meio. Ela foi também pioneira ao utilizar a eletricidade na separação, contagem e tabulação dos cartões. Os dados do censo de 1880, manualmente processados, levaram 7 ...
