Meaning of COMPRESSION in English

COMPRESSION

Has several meanings. In one context, it refers to algorithms for shrinking the storage space required for files stored on discs. In those instances, nothing is usually sacrificed in the compression, although files may have to be decompressed before they can be utilized later on. In another context, compression refers to the storage of graphics or video files in such a way that they can be stored and/or processed more efficiently on computers. In the latter case, something (e.g., color depth, resolution, image sharpness, etc.) is usually lost in the process. (See also GIF , JPEG , Indeo , and MPEG )
