[CentOS] Is it okay?

Hi,

I have downloaded the following version:

CentOS-5.5-i386-LiveCD-Release2.iso

from the mirror:

http://ftp.iitm.ac.in/centos/5.5/isos/i386/

What I want to ask is that 'Release2' is the complete OS and after
installation we can use 'yum update'. So at first, is it enough (as I
am not going to download the complete set of 7 CDs)?
