Popular Photography Magazine has a good article on File Formats that explain JPEGs, TIFFs and RAW files in an easy to understand way.
'When an image is captured by your camera's digital sensor, a series of settings are applied as alterations to the original raw data.

In addition to “alterations” for sharpness, white-balance, and the rest (which are either selected by the camera's default settings or set by you), the choice of file format that the image is saved in can have a profound affect on overall quality. Get it wrong, and there's little that can be done even in Photoshop.'
