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的文件传输的协议。 FTP和HTTP之间有很多区别。在本文中,我们将学习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。这是一个互联网标准,允许从互联网在不同计算机上进行文件下载和上传的过程。 FTP站点由不同类型的文件(文本,图形,视频,图像等)组成。它是在安全性不是大问题时开发的。它较旧,并已被新协议取代。 FTP支持两个单独的传输控制协议,第一个是用于验证用户身份的控制连接或命令端口(端口21),第二个是用于传输文件的数据连接或数据端口(端口20)。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WWW的骨干。这是一个互联网标准,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中都包含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。
