虚拟机是一个软件,其作用可以在一个操作系统中再运行一个或多个其它的操作系统,FTP是“File Transfer Protocol”的缩写,意思为文件传输协议。文件传输是指将文件从一台计算机上发送到另一台计算机上。如果用户要将一个文件从自己的计算机上发送到另一台计算机上,就可以使用FTP上传(upload),反之,称为FTP下载(download),而更多的情况是用户使用FTP下载。FTP服务器可以管理与控制用户访问FTP服务器的权力,这样可以使要下载或上传的文件更加安全和具有可控制性。

FTP is the abbreviation for “File Transfer Protocol”, meaning a file transfer protocol. File transfer refers to the file is sent from one computer to another computer. If users want to send a file from their own computer to another computer, they can use FTP to upload (upload), otherwise, called FTP download (download), and more often users download using FTP. The FTP server can manage and control the user’s access to the FTP server, which makes the files to be downloaded or uploaded safer and more controllable.
