On a spinning reel the drag adjustment controls the force needed to pull line off the reel by the fish.
Most flyreels have a drag adjustment to control this same issue, usually a
cork or metal pressure plate to put resistance on the spool as it turns in only1 direction, that being as the line is pulled out by the fish & the reels are free wheeling in the reel in direction.
Now the drag most people are talking about in fly fishing is the reaction of the water, different currents, on your fly line & leader & how it affects your fly's drift. The ideal drift is without any drag at all. If your leader & flyline are in front of your fly & bellying & pulling your fly in an unnatural manner, that's drag. You can control drag by flipping your flyline to a position where it doesn't affect the fly's drift giving the fly a more natural presentation to the fish. This is called mending the line & it's something you'll have to practice.
There are 3 basic types of rod actions & the easiest way to picture them is
Slow: As you cast the whole rod bends & flexes
Medium: As you cast the flex is more in the upper 2/3 of the rod.
Fast: As you cast the rod flex is more in the upper 1/3 of the rod.
This is a pretty basic description to help you visualize what they mean when they talk about a rod's action..
I hope this helps
