Data compression ratio — Data compression ratio, also known as compression power, is a computer science term used to quantify the reduction in data representation size produced by a data compression algorithm. The data compression ratio is analogous to the physical… … Wikipedia
Data compression — Data in computers are normally stored in a way which causes every character (including spaces) to occupy the same amount of memory space. This is usually an eight digit code consisting of 0s and 1s. As the amount of data needed to be held in… … International financial encyclopaedia
Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… … Wikipedia
Data compression symmetry — Symmetry and asymmetry, in the context of data compression, refer to the time relation between compression and decompression for a given compression algorithm. If an algorithm takes the same time to compress a data archive as it does to… … Wikipedia
data compression — Process of reducing the amount of data needed for storage or transmission of a given piece of information (text, graphics, video, sound, etc.), typically by use of encoding techniques. Data compression is characterized as either lossy or lossless … Universalium
Lossless data compression — is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be… … Wikipedia
Universal data compression — is impossible, though some claim to have found a way to do it. Any data compression algorithm necessarily leaves some input data uncompressed. A simple counting argument illustrates this.Suppose there is an algorithm A which compresses all data… … Wikipedia

Algorithm BSTW — The Algorithm BSTW is a data compression algorithm, named after its designers, Bentley, Sleator, Tarjan and Wei in 1986. BSTW is a dictionary based algorithm that uses a move to front transform to keep recently seen dictionary entries at the… … Wikipedia
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.

Data differencing — In computer science and information theory, data differencing or differential compression is producing a technical description of the difference between two sets of data – a source and a target. Formally, a data differencing algorithm takes as… … Wikipedia
