Who used punched cards practically for the first time in the history of computers?
The correct option is B Dr.Herman Hollerith
Dr.Herman Hollerith used
punched cards practically for the first time in the history of computers.
A punched card or punch
card is a piece of stiff paper that can be used to contain digital data
represented by the presence or absence of holes in predefined positions.
Digital data can be used for data processing applications or, in earlier
examples, used to directly control automated machinery.
Punched cards were widely
used through much of the 20th century in the data processing industry, where
specialized and increasingly complex unit record machines, organized into
semiautomatic data processing systems, used punched cards for data input,
output, and storage. Many early digital computers used punched cards, often
prepared using
Herman Hollerith
(1860-1929) was the inventor of the punched card tabulating machine-the
precursor of the modern computer-and one of the founders of modern information
processing. His machine was used to gather information for the 1890 census more
efficiently.
