FTP 和 HTTP 的区别

超文本传输协议 (HTTP) 和文件传输协议 (FTP) 是用于客户端和服务器之间文件传输的协议。 FTP 和 HTTP 之间有很多区别。在本文中，我们将了解 HTTP 和 FTP 之间的区别。

1.文件传输协议(FTP) ：
它代表文件传输协议。它是一种互联网标准，允许从互联网在不同的计算机上下载和上传文件。 FTP 站点由不同类型的文件(文本、图形、视频、图像等)组成。它是在安全性不是一个大问题时开发的。它较旧，正在被新协议取代。 FTP 支持两个独立的传输控制协议，第一个是控制连接或命令端口(端口 21)来验证用户，第二个是数据连接或数据端口(端口 20)来传输文件。它需要特定的用户名和密码才能访问。

2.超文本传输协议(HTTP) ：
它代表超文本传输协议。它是万维网的支柱。它是一种互联网标准，允许通过互联网传输网页的过程。它还定义了 Web 浏览器将如何响应任何 Web 请求。所有网页的网址都包含协议、域名和网页路径。大多数网址在其 URL 中包含 http:// 以显示 HTTP 协议。 HTTP 的工作方式类似于 FTP 和 SMTP 的组合功能。它还使用传输控制协议。
