网站的组成
Composition of the website
在早期，域名、空间服务器与程序是网站的基本组成部分，随着科技的不断进步，网站的组成也日趋复杂，目前多数网站由域名、空间服务器、DNS域名解析、网站程序、数据库等组成。
In the early days, domain names, spatial servers and programs were the basic components of websites. With the continuous progress of science and technology, the composition of websites became more and more complex. At present, most websites are composed of domain names, spatial servers, DNS domain name resolution, website procedures, databases and so on.
域名
domain name
域名（Domain Name），是由一串用点分隔的字母组成的Internet上某一台计算机或计算机组的名称。用于在数据传输时标识计算机的电子方位（有时也指地理位置），域名
Domain Name is the name of a computer or group of computers on the Internet, which consists of a series of dot-separated letters. Used to identify the computer's electronic location (sometimes geographic location) and domain name in data transmission
已经成为互联网的品牌、网上商标保护必备的产品之一。通俗的说，域名就相当于一个家庭的门牌号码，别人通过这个号码可以很容易的找到你。以一个常见的域名为例说明，baidu网址是由二部分组成，标号“baidu”是这个域名的主域名体，而最后的标号“com”则是该域名的后缀，代表的这是一个com国际域名，是顶级域名。而前面的www.是网络名， 为www的域名。
It has become one of the indispensable products for Internet brand and online trademark protection. Generally speaking, a domain name is equivalent to a family's door number, through which others can easily find you. Taking a common domain name as an example, the Baidu website is composed of two parts. The label "Baidu" is the main domain name of the domain name, while the last label "com" is the suffix of the domain name, representing a com international domain name and a top-level domain name. The previous www. is the network name, the domain name of www.
DNS规定，域名中的标号都由英文字母和数字组成。每一个标号不超过63个字符，也不区分大小写字母。标号中除连字符（-）外不能使用其他的标点符号。级别最低的域名写在最左边，而级别最高的域名写在最右边。
DNS stipulates that the labels in domain names are composed of letters and numbers in English. Each label does not exceed 63 characters and does not distinguish between upper and lower case letters. No punctuation except hyphens (-) can be used in labels. The lowest level domain name is written on the leftmost side, while the highest level domain name is written on the rightmost side.
空间
space
常见网站空间：虚拟主机，虚拟空间，独立服务器，云主机，VPS。
Common Web Site Space: Virtual Host, Virtual Space, Independent Server, Cloud Host, VPS.
虚拟主机是在网络服务器上划分出一定的磁盘空间供用户放置站点、应用组件等；提供必要的站点功能、数据存放和传输功能。所谓虚拟主机，也叫“网站空间”，就是把一台运行在互联网上的服务器划分成多个“虚拟”的服务器。每一个虚拟主机都具有独立的域名和完整的Internet服务器（支持WWW、FTP、E-mail等）功能。虚拟主机是网络发展的福音，极大的促进了网络技术的应用和普及。同时虚拟主机的租用服务也成了网络时代新的经济形式。虚拟主机的租用类似于房屋租用。
Virtual host is to divide a certain disk space on the network server for users to place sites, application components, etc. It provides necessary site functions, data storage and transmission functions. The so-called virtual host, also known as "website space", is to divide a server running on the Internet into several "virtual" servers. Each virtual host has its own domain name and complete Internet server (supporting WWW, FTP, E-mail, etc.). Virtual host is the gospel of network development, which greatly promotes the application and popularization of network technology. At the same time, the rental service of virtual hosts has become a new economic form in the network era. The rental of virtual hosts is similar to that of houses.
