Little Space for Things of Little Importance - Tinkering with Compression
Published:A compression algorithm can either be a lossless or a lossy algorithm. A compression algorithm is considered lossless when there is no information reduction after compressing; these kind of algorithms work by reducing statistical redundancy, e.g. by back-referencing repeated portions of the data. The ZIP format implements lossless compression. On the other hand, the lossy algorithms remove unnecessary data or noise from the original representation. The decompressed representation obtained after reversing a lossy compression is only an approximation of the original representation. MP3 uses lossy data compression
