I can try to help. Maybe we get too bogged down in the numbers and the computer science, which leaves out people who have other interests/background/priorities.
So here's the deal: GIF: Tiny files, few colors (max 256). Capable of transparency and animation.
JPEG: Maximum number of colors, but uses lossy compression (i.e. the original file is damaged by the compression). Small files, though. Compression is adjustable and there are tricks to minimize the appearance of damage.
TIFF: Maximum number of colors, but uses lossless compression, so the files are large. Good for archival use. (It's not uncommon to keep an "original" image in TIFF format and use a "production" image in JPEG format.)
PNG: A relatively new "best of all worlds" format. Maximum colors, lossless compression, and capable of transparency.
