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。
