That's "DB-25" and "DE-9". "D" is the shape, "B" or "E" the size, and "25" or "9" the number of pins. A "DA shell" has room for lots of pins, a "DF" not many.

Except that in practice, virtually nobody ever says DE-9.

Oh, lots of people get DE-9 right. And there's nothing to lose by saying it right even if most people don't.

If you want to see a connector name that is almost universally misused, look at RJ-45. Virtually everybody calls the 8P8C modular telephone connector RJ-45, even though the real meaning of RJ-45 (an ancient hookup standard for modems) is formally documented.
