qjackctl, aka Jack Control, is not the jack audio system, but a convenient GUI that helps configure and control 
the jack audio system or server, which runs in the background. jackd --version will tell you the jack version.

These ports are sort of  pulseaudio to jack bridges. Pulseaudio is the general purpose audio system in ubuntustudio.
