Are you talking about naming for the motherboards.
There is some logic to them. I used to have the Gigabyte naming scheme around here. Once you under that naming scheme for a particulare motherboard manufacture, it does make things a lot easier.
Like normally you got a series name for what generation of Processor
Eg.
Gigabyte GA-7 = Socket A
Gigabyte GA-8 = Pentium 4
Gigabyte GA-K8 = Socket 754/939
Gigabyte GA-9 = LGA775 socket
Gigabyte GA-M = AM2 socket
After those few letters, you then get the motherboard Chipset.
I = Intel chipset
S = SiS chipset
N = nVidia set
V = Via chipset
Normally after that is tends to go into the name of the chipset.
Eg. I945 mean that the motherboard as a Intel 945 Chipset on it.
After that, it just about any one guess on what the letters mean. And this can change from year to year.
Like one year M might mean Mutlimedia, and then the next year M means MicroAtx.
Typically when you see things like Pro, Neo, Platinium, Royal at the end, it means that motherboard is special and has a lot of extras that Joe Average might now use.
And finally you have Ver or Rev which is a Version or a Revision of the motherboard. As some times midway during the product life cycle they will do a minor change to the motherboard, our ever the change is so small that it does not warranty a entirely new motherboard name.
