Why do people phrase their questions as if it's a piece of college course work. rc in these cases means Release CANDIDATE. This essentially is a kernel that is nearing release and candidates are being put in place to see how ready that candidate/build is for release... a lot of software releases Release candidates as such, consider it similar to the last stages of Beta testing where you have what you believe is a finished product but just want to make sure there are no problems left and possibly ironing out those last few errors.
Essentially if there are no problems with the rc it will become the officially released version, if there are problems it might be changed to make another release candidate, this is why the candidate is released, to answer this question of "is it ready?".
