- Paper data storage
Paper data storage refers to the storage, on paper, of data that can be interpreted by a machine or is the result of the functioning of a machine. A defining feature of paper data storage is the ability of humans to produce it with only simple tools and interpret it visually. Though it is now mostly obsolete, paper was once an important form of
computer data storage .The earliest use of paper to store instructions for a machine was the work of
Basile Bouchon who, in 1725, used punched paper rolls to control textile looms. This technology was later developed into the wildly successfulJacquard loom . The 19th century saw several other uses of paper for data storage. In 1846, telegrams could be prerecorded onpunched tape and rapidly transmitted using Alexander Bain's automatic telegraph. Several inventors took the concept of a mechanical organ and used paper to represent the music. Similar technology, in the form of discretepunched card s, was used byHerman Hollerith for his tabulating machines built under contract for the 1890 US Census.The data tabulation industry and computer revolution of the 20th century led to several more uses of paper as a data storage medium. Hollerith's company later became
IBM and his cards were widely used with computers through the 1970s. Other technologies were also developed that allowed tabulating machines and computers to work with marks on paper instead of punched holes. This technology was widely used for tabulating votes and grading standardized tests. Barcodes made it possible for any object that was to be sold or transported to have some computer readable information securely attached to it.
