FTP is the English abbreviation for file Transfer Protocol (document Transfer Protocol), while Chinese is called "the Protocol". A two-way transmission of control files for use on the Internet. At the same time, it is also an application (application). It allows users to connect their PCs to all the servers running FTP protocols around the world and access a large number of programs and information on the server. The primary role of FTP is to have users connect to a remote computer (which runs an FTP server program) to see what files are on the remote computer, then copy the files from the remote computer to the local computer, or send the files from the local computer to the remote computer. FTP uses more than NFS, so you must be skilled in configuring it.
