如果你的计算机是连接到Internet上的,不管你用的是哪种计算机,也不管你用的是什么连接方式,有两个问题可以肯定:第一,你在使用TCP/IP网络协议;第二,你的计算机有一个唯一的Internet协议(IP, Internet Protocol)号码。没有这两者是不能访问Internet的。一般来说,TCP/IP协议没有什么问题,它通常在安装Windows的时候就一起安装了,或者也可以通过控制面板的网络项进行安装。但是计算机是怎么得到这个唯一的IP号码的呢?这就是个完全不同的问题了。
If your computer is connected to the Internet, no matter what kind of computer you are using or the type of connection you are using, there are two issues that you can be sure of: First, you are using the TCP / IP network protocol; Second, your computer has a unique Internet Protocol (IP) number. Without these two can not access the Internet. In general, TCP / IP protocol is no problem, it is usually installed together when installing Windows, or through the control panel network item to install. But how did a computer get this unique IP number? This is a completely different problem.
