Hello,
my sister just bought her computer but yesterday i was at her place and noticed one thing on her dvd rom.. it was written dvd+-rw and i spent hours in trying to understand what it really means?
ive never understood the meaning of these acronyms and if anyone could explain me please?
does it mean that the dvd rom can read and write on dual layer discs?

It means that it can read discs with the -symbol as well discs with the +symbol and sometimes these kinds of dvd rom can read and write on dual layer discs . most of the times +dvds are more easily available.
