                    each with its own color information. These graphics are resolution-dependent, and when you zoom in on a raster
                    image, you may notice a loss of quality and pixelation. The common file formats for raster graphics include JPEG,
                    PNG, and GIF.

                    the “AU” format, which stands for “Audio.”
                     .mpg is a file format associated with video files. It is part of the MPEG (Moving Picture Experts Group) family
                    of video compression formats. .mpg files typically contain compressed video and audio data and are used for
                    storing movies, video clips, and other multimedia content.
