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.
Punch card. Early method of data storage used with
early computers. Punch cards also known as Hollerith cards and IBM cards are
paper cards containing several punched or perforated holes that were punched by
hand or machine to represent data.
IBM still manufactures and services mainframes like
this Z10. It surprises some people to hear, but IBM still makes computers. They
don't make computers that run Windows, but they still make high-end computers
that run AIX, their version of Unix. They also make minicomputers and
mainframes.
