FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -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-2: -A punched card (also punch card or punched-card) is a piece of stiff paper that holds digital data represented by the presence or absence of holes in predefined positions. Punched cards were once common in data processing applications or to directly control automated machinery.

Detailed explanation-3: -During the U.S. Census of 1890, engineer Herman Hollerith used punch cards to save and count data on the population. Since a single punch card can only store 80 bytes of information, many cards were required for data storage and programming.

Detailed explanation-4: -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-5: -A punch card is a simple piece of paper stock that can hold data in the form of small punched holes, which are strategically positioned to be read by computers or machines. It is an early computer programming relic that was used before the many data storage advances relied upon today.
