Drywall and jiprock or sheet rock are the same thing. Filling holes depends a little on the nature of the holes. If they don't go right through then you just spread and force the mud right over the hole. You may need to spread a thin layer of plaster and embed paper tape into it to give better strength if it is badly cracked. If the hole goes through there are a number of different methods used depending on the size of the hole.
You may be able to just stuff some wadded paper in there and work plaster over it, you might work some adhesive tape to the back side of the jiprock with enough exposed sticky to hold a little paper to form a base enough to apply layers of the plaster mud allowing to dry as you build up the hole. Large holes may require you to cut a square out, screw some strips of wood onto the back side with screws through the board on the front overlapping enough to allow you to cut a filler piece and screw it into the strips of wood then apply a thin layer of plaster around the cracks and press paper tape firmly into the sticky mud before plastering over the lot including filling the screw holes. This usually takes a couple of applications because the plaster shrinks as it dries and the screw holes reappear through the first couple of applications. The paper tape is used to reinforce the cracks otherwise the shrinking plaster will form cracks which become visible. Many people now prefer the adhesive mesh tape. this is stronger but it is also thicker and I don't much like using it because it takes a lot more plaster to build up and hide the stuff and I find the lump left behind unacceptable. It isn't bad along the formed edges of drywall where there is a bit of a valley but across the ends and other butt joints requires more work than I like to do. You sand smooth and paint.

And filling up wholes in your wall? Hi, ok what is the difference between dry wall and sheetrock? Or are they the same thing? Also, a room that im in has quite a few wholes in the wall and i was wondering how do i go about fixing them? I know you can use sheetrock mud and patch them up but how exactly do you do it step by step? Do i just buy the mud if thats what its called, spread it throughout the wholes as evenly as posible, then wait for it to dry and take a piece of sandpaper and sand it down to be even with the rest of the wall? I know that after its done you have to pait over it but thats fine with me because this room needs to be repainted anyway. [Non-text portions of this message have been removed]
