TIFF isn’t really a file format, it is a wrapper class that allows for embedding images in several formats, in a somewhat similar fashion to PDF. So, from Photoshop, for example, you can save an image in TIFF using no compression, LZW (Lempel–Ziv–Welch, which is lossless), ZIP (which is lossless) or JPEG (which is lossy).

Very true.  However evey program i have ever used, defaults to saving a TIFF using no compression, which is lossless.  But like most things in life, not knowing what to ask gets us in big trouble... so everyone should always check.
