Answer:

Absolute pressure is the pressure measured from the void. Gage pressure is the pressure measured respect to the atmospheric pressure.

Step-by-step explanation:

Absolute pressure (as the name says) is an absolute reading, is the pressure measured from the void (considered the zero reference). Gage pressure is a relative reading, is the pressure measured respect to the atmospheric pressure (pressure minus atmospheric pressure).
