Card difference

卡差───Card difference

Daniel: Excuse me, How about IC card? What's the difference?───丹尼尔：请问，用IC卡是多少钱呢？有什么区别吗？

The only difference is the last case with the underscore ‘_’ wild card.───唯一的区别是最后一个case 使用了下划线'_' 通配符。

Therefore, it is important to know the difference between turning off a network card on a short-term basis with the ifconfig command versus dropping it with the chdev command.───因此，一定要了解用 ifconfig 命令短期关闭网卡与用 chdev 命令删除网卡之间的差异。
