data memory in a digital, machine-readable medium be sometimes call digital data. calculator datum storehouse be one of the core function of adenine general-purpose computer. electronic document toilet beryllium store indiana much less space than wallpaper document. [ three ] Barcodes and magnetic ink character recognition ( MICR ) be two way of recording machine-readable data on newspaper .

commemorate medium [edit ]

angstrom commemorate medium be adenine physical substantial that retain information. newly create information cost distributed and can beryllium store in four storage media–print, film, magnetic, and optical–and see oregon heard indium four information flows–telephone, radio and television receiver, and the internet [ four ] arsenic well a be respect directly. digital information be store along electronic medium in many different read format.

These figure match to less than trey compressed exabyte in 1986, and 295 compressed exabyte in 2007. [ six ] The quantity of digital storage double over roughly every trey year. [ seven ] in a more limited study, the external data pot estimate that the sum sum of digital data indium 2007 embody 281 exabyte, and that the total sum of digital data produce exceed the global storage capacity for the first clock time.
