I always thought that Mountboard was the board you mount the photo on - hence the term Dry Mounting for sticking the photo to the mounting board, while the Mat was the card that had the "window" cut out and acts as a frame around the print.
I think the question was about the differences in the board, and it is generally the same type of board that is used for either method, hence a sheet of matboard (or mounting board) is typically around 1-1.2mm thick with a coloured side and a white or cream core. The term "mat mounting" does refer to using an aperture in front of the image, so a "mat" would become so, only after the hole is cut out I guess, until then it is just a sheet of card and can also be used for dry mounting.
There are self coloured card sheets available, that don't have a white / cream core, and these can be used for sticking prints on to, but they are usually sold as coloured card, rather than mountboard.
My prints get two sheets of identical card when mounting, I use 1.2mm cardstock, with a white core for both the cut out mat on the front and the (uncut) backing board.

Maybe POTN can start a movement to rename mat (or mount?) to window and mount (or mat?) to backing board!
.
Well, it's the same stuff most of the time (although you can use thinner self coloured card for backing of course). It becomes a mat when you cut a hole in it.

Coincidentally, 'dry mounting' implies there's a 'wet mounting' - is that so?
Yes, although it is normally called gluing, rather than wet mounting. There are several ways of sticking prints to a card. You can use double sided adhesive tape, you can glue it with a variety of different glues or you can dry mount it. Dry mounting is the best way to avoid wrinkles as glue etc., can cause the print to wrinkle up as it dries, if not applied properly.
Dry mounting is still a form of gluing but, rather than a liberal application of "wet" glue, it uses a drymounting tissue which is placed between the print and the backing. The tissue is essentially a very thin sheet of adhesive which needs to be heated to work (until then it is just a sheet of tissue and can be handled without any stickiness). You place it between the print and the board and place everything into a heated press to apply pressure as it is heated.
You need to set the thermostat to the appropriate temperature and then apply the heat and pressure for the recommended time (temperature and time vary depending on the tissue you are using, instructions will be supplied with the tissues).
The very thin, uniform, layer of glue and the way it works with heat and pressure, ensure a very flat result that won't wrinkle over time.

I'm still not 100% certain of how you attach the photo to backing board and window - I should read the book that came with the Logan cutter.
There is some degree of personal preference here. I know someone who uses double sided adhesive tape around the edge of the print (you need to allow some extra print surface for this of course, around the outside of the aperture). Personally (and most people I know do the same) I just stick it on with tape around the back of the print, making sure it is aligned correctly in the aperture first of course. I don't use archival quality tape, or acid free this and that, but mu prints don't need to last a long time, as they are going to competitions and as exhibition entries and will be retired after a relatively short while as the mounts can get a bit tatty, and grubby, being carted here, there and everywhere and with a lot of people handling them. If you intend them to be framed and hung for a long period, or sold, then I would think it worth looking into archival quality materials.
Personally, I tape around all four sides then glue the backboard on with a liberal application of "pritt stick" type glue around the edges. I have had no problem with wrinkling, but the idea that someone mentioned above of just taping the top edge could be worth looking into, if that is a concern, or you are having trouble keeping the print level while you tape it down.
