计算机通信常用协议端口
端口(port)对硬件设备来讲可以是USB端口、COM串行端口或交换机、路由器设备的对外连接端口。而对软件来讲端口是通信协议之间的接口，其定义了
UNIX或WINDOWS NT系统的所提供的服务。本地系统会为所提供的服务进程分配相应的端口号，也就是协议端口号。
协议端口号用正整数标识，范围在0到65535之间。0-1023之间的端口为知名端口，这些端口一般固定分配给一些服务,比如21端口分配给FTP服
务，23端口分配给TELNET,80端口分配给HTTP服务；而1024到65535之间的端口为动态分配端口，这些端口一般不固定分配给某个服务，也
就是说许多服务都可以使用这些端口。只要运行的程序向系统提出访问网络的申请，那么系统就可以从这些端口号中分配一个供该程序使用，在关闭程序进程后，就
会释放所占用的端口号。
根据TCP/IP协议，端口又分为TCP端口和UDP端口两种：TCP端口和UDP端口。
TCP端口，即传输控制协议端口，是面向连接的服务端口，需要在客户端和服务器之间建立连接，以提供可靠的数据传输。常见的如FTP服务的21端
口，Telnet服务的23端口，SMTP服务的25端口等等。
UDP端口,即用户数据包协议端口，是面向非连接的服务端口，无需在客户端和服务器之间建立连接。常见的如DNS服务的53端口，TFTP服务的69端
口，QQ使用的8000和4000端口，SIP使用的5060端口等等。下面是常用的协议端口：
