storing graphic data

bitmap, is a type of memory organization or image file format used to store digital images on Microsoft Windows and OS/2 operating systems. It is uncompressed; therefore the file sizes are much larger than those for other formats. Can store graphics from 1-bit (2-color, ie black and white) up to 24-bit (16.7 million colors)

GIF, is a bitmap image format for pictures with up to 256 distinct colours.. file format used for raster, or bit map, artwork, primarily for the web. It is mostly suitable for graphics and to a lesser extent for photo’s.

JPEG, is named after the ‘Joint Photographic Experts Group’, who created the standard. It is a commonly used method of lossy compression for photographic images. Is useful for making high-quality photographic – style images of relatively small file size. Primarily used to compress photographic images. JPEGs reduce the original image size by subdividing and simplifying complex images, allowing them to transfer more quickly across an internet connection.
