硬件部分，web 服务器是一台存储了 web 服务器软件以及网站的组成文件（比如，HTML 文档、图片、CSS 样式表和 JavaScript 文件）的计算机。它接入到互联网并且支持与其他连接到互联网的设备进行物理数据的交互。

In terms of hardware, a web server is a computer that stores web server software and files that make up a website (e.g., HTML documents, images, CSS style sheets, and JavaScript files). It is connected to the Internet and supports physical data interaction with other devices connected to the Internet.

基本上，当浏览器需要一个托管在网络服务器上的文件的时候，浏览器通过 HTTP 请求这个文件。当这个请求到达正确的 web 服务器（硬件）时，HTTP 服务器（软件）收到这个请求，找到这个被请求的文档（如果这个文档不存在，那么将返回一个 404 响应），并把这个文档通过 HTTP 发送给浏览器。

Basically, when a browser needs a file hosted on a web server, the browser requests the file via HTTP. When the request reaches the correct web server (hardware), the HTTP server (software) receives the request, finds the requested document (if the document does not exist, a 404 response is returned), and sends the document to the browser via HTTP.

要获取一个网页，你的浏览器会向网络服务器发送一个请求，服务器会在自己的存储空间中搜索所请求的文件。找到文件后，服务器读取文件，根据需要进行处理，并将其发送给浏览器。让我们更详细地了解一下这些步骤。

To get a web page, your browser sends a request to a web server, which searches its own storage for the requested file. Once the file is found, the server reads it, processes it as needed, and sends it to the browser. Let's look at these steps in more detail.

通过 HTTP 交流
其次，web 服务器提供了 HTTP（Hypertext Transfer Protocol，超文本传输协议）支持。正如它的名字暗示，HTTP 明确提出了如何在两台计算机间传输超文本（链接的 web 文档）。

协议是一套为了在两台计算机间交流而制定的规则。HTTP 是一个文本化的（textual），无状态的（stateless）协议。

Communicate via HTTP
Second, the web server provides support for HTTP (Hypertext Transfer Protocol). As its name implies, HTTP specifies how to transfer hypertext (linked web documents) between two computers.

A protocol is a set of rules for communicating between two computers. HTTP is a textual, stateless protocol.

粗略地说，一个服务器可以提供静态或者动态的内容。静态意味着“保持原样地提供”。静态的网站是最容易建立的，所以我们建议你制作一个静态的网站作为你的第一个网站。

“动态”意味着服务器会处理内容甚至实时地从一个数据库中产生它。这个方法提供了更多的灵活性，但技术栈更加复杂，使得建立一个网站的挑战大大增加。

Roughly speaking, a server can serve static or dynamic content. Static means "serve as is". Static websites are the easiest to build, so we recommend you make a static website as your first website.

"Dynamic" means the server processes the content and even generates it in real time from a database. This approach offers more flexibility, but the technology stack is more complex, making building a website much more challenging.

僵尸网络一般由黑客、控制协议、跳板主机、僵尸主机组成，僵尸网络的控制者通过特定的控制协议与僵尸主机上的客户端通信，从而远程控制僵尸网络上的僵尸主机。
