If I were to use a DVI/VGA adapter on a VGA port on my computer, would my computer consider it as digital because of the adapter or analog because of the port?

Once converted to vga it's then an analog signal.

No, it will not convert the analog signal to digital.

DVI can be digital or analog. By placing a DVI->D-Sub adapter on the line you are forcing a purely analog signal to be sent to the monitor.
