Barron’s Business Dictionaries - All books in this series
This updated edition includes the most recent terms relating to constantly expanding computer and internet technology.
More than 3,200 terms and definitions deal with:
DATA COMPRESSION the storage of data in a way that makes it occupy less space than if it were stored in its original form. For example, long sequences of repeated characters can be replaced with short codes that mean "The following character is repeated 35 times," or the like. A more thorough form of data compression involves using codes of different lengths for different character sequences so that the most common sequences take up less space. Most text files can be compressed to about half their normal size. Digitized images can often be compressed to 10 percent of their original size (or even more if some loss of fine detail can be tolerated), but machine-language programs sometimes cannot be compressed at all because they contain no recurrent patterns. See also ZIP FILE; STUFFIT; PCX; JPEG; MPEG.
