Detailed explanation-2: -Herman Hollerith’s tabulator consisted of electrically-operated components that captured and processed census data by “reading” holes on paper punch cards.
Detailed explanation-3: -Herman Hollerith’s first tabulating machines opened the world’s eyes to the very idea of data processing.
Detailed explanation-4: -Herman Hollerith invented and developed a punch-card tabulation machine system that revolutionized statistical computation. Born in Buffalo, New York, Hollerith enrolled in the City College of New York at age 15 and graduated from the Columbia School of Mines with distinction at the age of 19.
Detailed explanation-5: -A tabulating machine working is based on reading one punch card at a time, then printing sections (fields) of the punch card on fan-fold paper, rearranging them, and then adding or assigning more numbers to the punched cards to one or more multiple counters, called accumulators.
