(1) What is the difference between Centos-xxxx-livecd.ios and Centos-xxxx-bin-dvd.iso? The former is only 700M and the latter has 3.8G. The difference is not only in size, its more essential difference is that Centos-xxxx-livecd.ios can only be loaded into memory to run, can not be installed. Centos-xxx-bin-dvd1.iso can only be installed on the hard drive.
