Punched cards were first introduced by ___________.
Punched cards were first introduced by ___________.
The correct option is D Herman Hollerith
Punched cards were first introduced by Herman
Hollerith.
The standard punched card, originally invented by
Herman Hollerith, was first used for vital statistics tabulation by the New
York City Board of Health and several states. After this trial use, punched
cards were adopted for use in the 1890 census. Hollerith wasn't working in a
vacuum.
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.[1][2] Many early digital computers used punched cards, often prepared
using keypunch machines, as the primary medium for input of both computer
programs and data.
