In brief: Either or both
General anesthesia is a state of unconsciousness and lack of reaction to painful stimuli.
It can be brought on by intravenous medications such as propofol, sodium pentothal, and ketamine. Anesthesia gases (desflurane, sevoflurane) will also produce general anesthesia. Often you will receive a combination of both during surgery.

In brief: IV to start
Usually a general anesthetic is started with medications given through the iv, and then transitioned to medications given via an endotracheal tube.
These would be the anesthesia gasses.

In brief: A balanced
General anesthetic usually combines intravenous and inhaled medications.
It is also possible to use only gases or only intravenous medications.

In brief: Both
Usually a general anesthetic involves both a gas that one would inhale, and intravenous medications given through an IV site.
