A truss rod keeps the neck straight by countering the pull of the strings and natural tendencies in the wood. When the truss rod is loosened, the neck bends slightly in response to the tension of the strings. Similarly, when tightened, the truss rod straightens the neck by resisting string tension.

Also to know is, how do I know if my guitar has a truss rod?
Now to answer your question, the easiest way to tell if your guitar has a truss rod which it does, is to look at the back of the neck. If it has a stripe of a different usually darker wood such as Rosewood going the length of the neck in the middle of the neck then that's one way to tell.
Similarly, how does a single action truss rod work? A single-action truss rod moves the neck in one direction (Fig. 2). By tightening the rod, you force the neck into a convex shape known as “back-bow.” Conversely, when you loosen the rod, it relieves the tension inside the neck and the strings will pull the neck forward, creating a concave shape called “fore-bow.”
Subsequently, one may also ask, what is a standard truss rod?
Most Fender guitars and basses are equipped with a “Standard” truss rod (there are two types of “Standard” truss rod; one which adjusts at the heel of the neck and one which adjusts at the headstock, but both operate on the same principle).
Can you adjust the truss rod with strings on?
You can adjust the truss either way, with the strings tuned to pitch or downtuned. Just be sure to retune it to the correct pitch once you make the adjustment. Also, put a drop or two of some light machine oil onto the threads where you'll be turning the truss.
