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

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 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 — 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
data compression — Any method of encoding data so that it occupies less space than it did in its original form, thus allowing that data to be stored, backed up, retrieved, or transmitted more efficiently. Data compression is used in fax and many other forms of… … Dictionary of networking
