See also Drew Neil's post on the use of the term "window" in vim

A Vim window is a "viewport on a buffer". A buffer is a file loaded into memory for manipulation. A viewport is what exactly? Logically it would seem that it is text displayed in vim/gvim. That text can be either the contents of a buffer, or something else... such as what? Perhaps output from commands?
