孙鑫老师vc教学视频中源码，以及上课所用ppt,非常好，希望对大家有用(Sun Xin vc teachers teaching video source, and the school used ppt, very good, want to be useful)

圆的绘制，在很多计算机课程中会用到元的绘制，特么是在计算就行雪中会有(Draw a circle, in many computer programs will be used to draw elements, especially in the calculation of what is on the line there will be snow)

包过滤路由器与包过滤防火墙具有同一功能，如2。1。1部分所述。 The packet filter rout provide the same functionality as the packet filter firewall describe in section2.1.1. 代理防火墙比包过滤器防火墙易于保持更多的上下文 The proxy firewall maintain context more easily than the packet filter firewall. 防火墙计算机要求2张以太网卡，一个对外部世界的接口和一个对主POP网络的接口。 The firewall machine will require two ethernet card, one interface to the outside world and one to the master pop network. (The firewall machine will require two ethernet card, one interface to the outside world and one to the master pop network. )
