JPEG

The term actually stands for "Joint Photographic Experts Group," because that is the name of the committee that developed the format. But don't try to remember this becuase even computer nerds will think you're weird if you mention what JPEG stands for. Instead, remember that a JPEG is a compressed graphic file format. JPEG compression is much better for compressing graphics with photographic color depth than GIF compression is. So, if you see a really colorful image on the web, it is most likely in JPEG format. JPEGs are not limited to a palette of 256 colors like GIFs are, but JPEG is a "lossy" format, which means some quality is lost when the image is compressed. Like GIFs, JPEGs are cross-platform, meaning the same file can be viewed equally on both a Mac and PC.
