Ah, in that case, I think the answer is "it depends".  :-)  Periodic 
updates and updates from one minor release to the next seem to use only 
a small amount of bandwidth and involve a small number of packages.  It 
is approximately the same as you would experience with RedHat Enterprise 
Linux, which is the basis for CentOS.  Compared to Fedora, the changes 
are significantly less often (except for security fixes) and probably a 
lot less bandwidth requirements (but I do not currently use Fedora so I 
am not positive about this part).

I hope that helps.
