Components of the Web

Your browser makes requests via the Internet to servers. These requests are using a protocol called HTTP. And the servers respond with files that the browser displays.

我們的瀏覽器會透過網路發送 request 到伺服器，這些 request 用的傳輸協定是 HTTP，然後伺服器會 respond 檔案到用戶的伺服器。

Some examples of browsers include Chrome, Safari, Firefox, Internet Explorer, and Edge. You're probably running one of those right this moment.

瀏覽器像是 Chrome, Safari, Firefox, Internet Explorer, 和 Edge

These servers are computers just like yours except they are optimized for sitting in a closet and hosting files rather than sitting on your desk browsing these files. And the protocol HTTP is just a very simple protocol that your browser uses to communicate with these servers. We'll mostly be focusing on the browser component in this section for rendering HTML files.

伺服器就像你的電腦但是他是擺在機房的櫃子，掌管許多檔案。HTTP 讓瀏覽器與伺服器溝通，下面這張圖可以表達瀏覽器、伺服器與、HTTP 與網路的關係。
