中文大致理解

liveDVD版本：它就是一个体验版，无需安装到硬盘，插入光盘就可以通过光盘软件并体验Centos的各种功能。

liveCD版本：和liveDVD一样，也是一个体验版和DVD体验版唯一的区别就是CD的存储空间要小一些，文件也会小一些，里面的软件包少一点。

bin-DVD版本：这个版本就是普通的安装版本发，如果需要给服务器安装一个centos系统到硬盘，就需要选择这个版本。这个版本的文件很大，so包含了大量的常用软件，这样安装系统时候就可以直接安装而无需从网络上再去下载了。

minimal版本：和bin-DVD一样它也是一个安装版镜像文件，只是minimal这个文件中只包含了系统和系统必须的几个基本软件包。

netinstall版本：和bin-DVD一样它也是一个安装版镜像文件，但是netinstall的软件包都需要通过网络下载进行安装而bin-DVD镜像自身包含了离线的软件包无需下载。

建议看英文。
