Data File

A data file is a computer file which stores data to use by a computer application or system. It generally does not refer to files that contain instructions or code to be executed (typically called program files), or to files which define the operation or structure of an application or system (which include configuration files, directory files, etc.); but specifically to information used as input, or written as output by some other software program. This is especially helpful when debugging a program.

Most computer programs work with files. This is because files help in storing information permanently. Database programs create files of information. Compilers read source files and generate executable files. A file itself is a bunch of bytes stored on some storage device like tape, magnetic disk, Optical disk etc. The data files are the files that store data pertaining to a specific application, for later use.

Famous quotes containing the words data and/or file:

    This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.
    Susan Sontag (b. 1933)

    A common and natural result of an undue respect for law is, that you may see a file of soldiers, colonel, captain, corporal, privates, powder-monkeys, and all, marching in admirable order over hill and dale to the wars, against their wills, ay, against their common sense and consciences, which makes it very steep marching indeed, and produces a palpitation of the heart.
    Henry David Thoreau (1817–1862)
