怎么查看自己的电脑里开了哪些端口，又怎么控制这些端口的打开或者关闭啊？

控制端口用防火墙就可以了啊,ice sword 也行

查看自己的电脑里开了哪些端口，可以通过以下方法，进行查看：
　　1、单击“开始”——“运行”，输入“cmd”，单击“确定”按钮，打开命令提示符。
　　2、在命令提示符界面下，输入CMD命令“netstat-an”，回车。
　 3、可以看到本机开放的所有TCP及UDP端口。

　　端口其实就是队，操作系统为各个进程分配了不同的队，数据报按照目的端口被推入相应的队中，等待被进程取用，在极特殊的情况下，这个队也是有可能溢出的，不过操作系统允许各进程指定和调整自己的队的大小。
