In computer science and information theory, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation. Compression can be either Lossy compression|lossy or Lossless compression|lossless. Lossless compression reduces bits by identifying and eliminating Redundancy (information theory)|statistical redundancy. No information is Loss (information theory)|lost in lossless compression. Lossy compression reduces bits by identifying marginally important information and removing it. The process of reducing the size of a data file is popularly referred to as data compression, although its formal name is source coding (coding done at the source of the data, before it is stored or transmitted). Compression is useful because it helps reduce resources usage, such as data storage space or transmission bandwidth (computing)|capacity. Because compressed data must be decompressed to use, this extra processing imposes...
