A bit simplistic, but not entirely inaccurate...

Not really. It's better to think of a font as a series of vector
images, each image describing a single glyph (character/letter) in the
font. In addition, a font contains data (hinting) that can tell a font
renderer how to improve the look of the vector information at certain point
sizes.

Boy are you working from REALLY OLD information!!!
The need for separate fonts (screen vs. printer) hasn't been true
for YEARS (about 10, actually) on either the Mac or Windows
platforms. Since the advent of TrueType and Adobe Type Manager, the EXACT
SAME fonts are used for both screen and print!

That's true - so at least you got one thing correct ;)

Both Type 1 and TrueType fonts only have a single set of data
associated with them - the vector information. That vector info is used
both for screen and printer.
