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.
