Portable Networks Graphic (.png):  

Portable Network Graphics (PNG) is a raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for Graphics Interchange Format (GIF), and is the most used lossless image compression format on the Internet.

Tagged Image File Format (.tiff):  

The ability to store image data in a lossless format makes a TIFF file a useful image archive, because, unlike standard JPEG files, a TIFF file using lossless compression (or none) may be edited and re-saved without losing image quality. This is not the case when using the TIFF as a container holding compressed JPEG.

width, and depth  (x, y, and z).

 

DPI:

acronym for Dots Per Inch - a gauge of visual clarity on the printed page or on the computer screen.
