  Compression \Com*pres"sion\, n. [L. compressio: cf. F.
     compression.]
     1. The act of compressing, or state of being compressed.
        "Compression of thought." --Johnson.
        [1913 Webster]
  


     2. (Computers) reduction of the space required for storage
        (of binary data) by an algorithm which converts the data
        to a smaller number of bits while preserving the
        information content. The act of compressing [3].
  
     Note: Compression may be {lossless compression}, in which all
           of the information in the original data is preserved,
           and the original data may be recovered in form
           identical to its original form; or {lossy compression},
           in which some of the information in the original data
           is lost, and decompression results in a data form
           slightly different from the original. {Lossy
           compression} is used, for example, to compress audio or
           video recordings, and sometimes images, where the
           slight differences in the original data and the data
           recovered after {lossy compression} may be
           imperceptable to the human eye or ear. The {JPEG}
           format is produced by a {lossy compression} algorithm.

  JPEG \JPEG\ n. [Acronym from Joint Picture Experts Group.]
     (Computers)
     A standardized format for storing graphic data in binary
     computer files, allowing over 16 million different colors. It
     allows for lossy compression, i. e. the compression of data
     into a form which re-expands into an image close, but not
     identical to the original image. Files stored in this format
     usually carry the extension jpg or jpeg. Compare {GIF}.
