8080端口为被用于>
在NCSA服务器中,端口号可以在0~65535之间选择,但是服务器管理员需要对服务器进行设置,以便只有一个端口可以被识别。网页服务的默认端口号是80。试验性的页面服务有时也在8080号端口运行。80端口被固定给Web服务,它是超文本传输协议中定义的端口,用来提供网页Web服务。

而8080,一般用与webcahe,完全不一样的两个,比如linux服务器里apache默认跑80端口,而apache-tomcat默认跑8080端口,其实端口没有实际意义只是一个接口,主要是看服务的监听端口。
80端口主要用于)即万维网传输信息的协议。可以通过>

是一组芯片内部集成vxworks联入式爆作系统,通过一个标准尺J45接口连接到工作环境的交换机。只要将服务器接入网络并且没有断开服务器的电源,不管HP服务器的处于何种状态(开机、关机、重启),都可以允许用户通过网络进行远程管理。中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口,我们就可以获取天气信息了。
关于获取天气预报的实例参考android学习手册,里面有源码。android学习手册包含9个章节,108个例子,源码文档随便看,例子都是可交互,可运行,源码采用android studio目录结构,高亮显示代码,文档都采用文档结构图显示,可以快速定位。360手机助手中下载,图标上有贝壳
中国国家气象局天气预报接口总共提供了三个:

注:上面接口201434日已不再更新。换成这个:>
最详细的信息来自第三个接口。上面url中的101010100是城市代码,这里是北京的城市代码。只需要改变城市代码,就可以得到所在城市的天气信息。笔者在福州,所以选择的城市代码是福州101230101。

FTP 是File Transfer Protocol(文件传输协议)的英文简称,而中文简称为“文传协议”。用于Internet上的控制文件的双向传输。同时,它也是一个应用程序(Application)。基于不同的 *** 作系统有不同的FTP应用程序,而所有这些应用程序都遵守同一种协议以传输文件。在FTP的使用当中,用户经常遇到两个概念:"下载"(Download)和"上传"(Upload)。"下载"文件就是从远程主机拷贝文件至自己的计算机上;"上传"文件就是将文件从自己的计算机中拷贝至远程主机上。用Internet语言来说,用户可通过客户机程序向(从)远程主机上传(下载)文件。
DHCP服务器是指由服务器控制一段IP地址范围,客户机登录服务器时就可以自动获得服务器分配的IP地址和子网掩码。
通俗点说,DHCP服务器就是自动给电脑分配IP地址和子网掩码的服务器。比如我们设置了路由器的DHCP服务器,让DHCP服务器自动分配IP地址,从1921681100到1921681199(子网掩码会自动设置,我们无需设置)。
如果用户在路由器设置中,关闭了DHCP服务器功能,不启用就必须手动给每一台连接这个路由器的电脑设置本地连接里面的“internet协议”。不启用比启用要麻烦一些,不过,如果你要通过路由器管理每一台电脑的话,不开启就方便一些,但需要手动给每一台电脑设置一个本地IP地址。
简单来说,DHCP服务器最大的好处就是可以防止局域网内电脑的IP地址冲突,防止IP冲突,网络不稳定。如果我们手动分配IP地址,电脑多了,很多可能会分到重复的IP地址,改起来就麻烦了。使用了DHCP服务器自动分配IP的功能,就可以避免这个麻烦,由路由器统一分配IP地址。DHCP服务器把每个IP地址只分给一台电脑,这样就能保证局域网的稳定性。

路由器DHCP服务器配置教程
在路由器设置中,用户可以对DHCP服务器进行相关设置,包括启用或关闭,另外还可以设置本地IP地址池的开始地址和结束地址等等,下面一起来看看设置教程。
1、首先在连接路由器网络的电脑或手机设备上,打开浏览器,然后登陆路由器的登陆网址,并输入密码登录,一般是19216811,不同路由器登录网址有所不同,请以路由器底部铭牌上的标注为准。
2、进入路由器设置界面后,在设置中,就可以找到DHCP服务器设置,用户可以对“DHCP服务器”启用或关闭进行配置,也可以是自动,一般普通用户,默认设置为“开”即可,地址池开始地址和结束地址也可以进行设置,如下图所示。
以上就是路由器DHCP服务器设置教程,对于普通用户来说,一般都无需去单独设置这个,默认是开启的,如果需要关闭,那么需要对电脑的本地IP地址进行单独设置,相对来说比较折腾,非专业局域网管理用户,建议还是不要去修改相关设置。
