Question

what concept of computing did herman hollerith to find a faster way to compute Us census.

Answer 1

Answer:

Herman Hollerith (1860-1929) was an American inventor of electronic punched card tabulating machine which opened the world’s eyes to the idea of data processing and later accounting.

Explanation:

• Hollerith’s machine was a precursor of the modern computers.

• The punch card was based on the counting and recording of the holes present or absent at a particular location on the card. In other words, this system was analogous to our binary system of ones or zeroes.

• Initially Hollerith sold these machines under his own name but form 1890 he started giving the machine to the U.S. Census office on a contractual basis. This did the job in just 2 years. Thus, the process of census became less tedious, less time consuming and saved a lot of money of the Census Office.

• Working of the machine: The card was around 3-7 inches and held data of one person. The details of the census were read from the census rolls and punched on to the cards by a clerk. Then the machine operator placed the card on to the machine and close the cover. This made the pins to get in contact with the mercury filled small cups and complete the electric circuit. These electric impulses helped the counter to count and record the results on to the counter board.  

• In the coming future this invention made remarkable expansions in other fields like U.S. military, agriculture, rail road freights, which led to the increase in the sales of the machine, brought more income, which was in turn used for the advancement of the machine.
