As a graphic/web designer, resolution for me is defined as dpi or dots per inch.

The medium used to publish detemines what resolution used to design in. For web it is typically 72 dpi while for print it is 300dpi.

This huge difference in resolution means that what is created for the web can’t be magically turned into a beautiful 300 dpi image ready for print .. and what happens if you try? You end up with a jagged, dotty, blurry print.
