Computer Science 4 5 6 Iii Pdf Data Compression Computer Data Data compression refers to the process of encoding information with the explicit purpose ofminimizing its memory transmission capacity requirements. Mpeg 4 (mp4) files are slightly different to mp3 files. this format allows storage of multimedia files rather than just sound. music, videos, photos and animation can all be stored in the mp4 format. videos could be streamed over internet using mp4 format without losing any real noticeable quality. exam style questions.
