Related introduction:

File Transfer Protocol (FTP) is a set of standard protocols for file transfer on the network. It works on the third level of the OSI model. Layer seven, the fourth layer of the TCP model, the application layer, uses TCP transmission instead of UDP. The client must go through a "three-way handshake" process before establishing a connection with the server to ensure that the connection between the client and the server is reliable. It is connection-oriented and provides reliable guarantee for data transmission.

FTP allows users to communicate with another host through file operations (such as adding, deleting, modifying, checking, transferring files, etc.). However, users do not actually log in to the computer they want to access and become a full user. They can use FTP programs to access remote resources, allowing users to transfer files back and forth, manage directories, access emails, etc., even though the computers on both sides may have different configurations. operating system and file storage method.
