Whats does the "J" in "JUSB" stand for?

[haris262]

I don't know if this is a thing in all motherboards, I have seen many that name their ports with a "J" in front. Like for example you would have "JUSB" (internal USB) "JAUD" (internal audio) "JFP" (for front panel connections) and many more. My questions is this, what exactly does that "J" stand for?

Thank you for the help!

"Jumper" - they use the same kind of pin headers as jumpers.
