quick question about quality

Hi, I have a couple quick questions about sound quality. First, if I back up my music by burning a Data CD on iTunes will I lose any quality when I put the music back on iTunes or will it maintain the 192 kbps quality that I ripped the music at? Secondly, if I have some music ripped onto my computer in Apple Lossless format and I burn a CD using this music am I correct in assuming I don't lose any quality? And would it also be correct to assume that I still won't lose quality if I rip it back to the computer in Lossless format again?
