一、啥是服务器?
服务器其实就是一个一直开机的电脑~
它里面存着很多文件和数据。每一个服务器都会有一个自己的固定ip地址,这是找到它唯一的途径!
二、啥是ip?
ip就像一个门牌号一样,告诉服务器告诉大家我在哪~比如我们可以ping度娘的官网~我们就能发现他的ip,如果我们直接用他的ip访问也是可以的。但是如果我们一直用这样一串数字来访问网页,那是不是会很蛋疼呢?所以我们要用 - 域名!
注:下图的亮点在地址框~用ip直接访问度娘~

三、啥是域名?
刚才和大家讲了ip,但是我们似乎没用过ip去访问度娘,那是因为人家用了域名的!
其实,域名就是帮助你把ip换成一段可以更好记忆的文本 ~ 比如baidu.com难到不比200.181.111.37 这样的9位数字好记忆?所以,你在浏览器的栏里输baidu它就会自动变成这9位数,这是不是方便很多~但是,它是怎么改变的呢?答案就是DNS
四、啥又是DNS?
DNS其实是域名系统(domain name system)的缩写。说白了,当你在浏览器的栏里输入域名时,它会先到dns去找这个域名所对应的ip,这样就完成了从ip到域名的转换,也完成了从数字到文本的转换。

五、啥是网站?
网页其实就是一个文件,就像ppt一样,只不过,ppt用office打开,而网页要用浏览器打开。相同,文件总有个存储的位置。比如,c盘/windows/用户/桌面。而网页也要有个自己的存储位置才能找到,而不同的是,这个位置是在服务器上的。那怎么找到它呢?其实很简单,那就是ip啊!我们通过ip就可以访问这个服务器了。比如贴吧的主页就是 tieba/index.html 也就是说,这个主页是在根目录下的index。html文件~和盘根目录下的一个ppt文件类似(其实服务器网页并不是在根目录~)
那你访问度娘的整个过程就可以这样去想像~~
你想要去查看别人电脑(服务器)里的一个文件(网页文件),那你要先找到他对吧。那怎么才能找到他呢?就是用ip,当你知道他的ip是不是就能找到他了,但是一串数字太难记了,于是用这个ip绑定一个域名,比如www.baidu.com这样,你只要用baidu.com,它就会在DNS上转换成百度度的ip地址了,于是我们就能看到他的文件了(网页文件)
当你了解了这些,我们现在就可以入门了~
接下来,你可以去了解墙的工作原理了
