Punch Card

                        The first punch card for giving instructions to machines - the forerunners of today's computer cards - were used in the textile mills of France in the early eighteenth century. A loom designed by Basile Bouchon in 1725 used holes punched in a roll of paper to weave designed into silk fabric. When the paper was pressed against a row of needles. the needles lining up with the holes stayed in place, while the others moved on.
