Both Type 1 and TrueType allow for it. TrueType has special mechanisms
built in: it has both extra hints for small sizes (which can squeeze
or stretch the characters) and the ability to include hand-tuned bitmaps
for REALLY small sizes.

"Smaller" is different. Prior to computer typesetting (and even in the
early days of computer typesetting), printers had to buy different 
sizes as separate fonts. Software "scalable fonts" (which should have
correctly been called "scalable typefaces") changed the economics,
but the meanings of the terms haven't changed.
