I. what is the course (comprehensive introduction)

1, Introduction:
FTP (file Transfer Protocol), which is the short name of the document transfer Protocol. Used for two-way transmission of control files on the Internet. At the same time, it is also an application (application). It allows users to connect their PC to all servers running the FTP protocol around the world, accessing a large number of programs and information on the server.
2. Function:
The primary role of FTP is to have users connect to a remote computer (which is running an FTP server program) to see what files are available on the remote computer, then copy the files from the remote computer to the local computer, or send the local computer's files to the remote computer.
3. Principle:

Take the file as an example, when you start FTP copy files from a remote computer, you actually launch two programs: a local FTP client program: It asks the FTP server for a copy of the file. The other is the FTP server program that launches on the remote computer, and it responds to your request to transfer the files you specified to your computer.

II. objectives of the project training

1, this series of lectures are divided into three parts:


Take the file as an example, when you start FTP copy files from a remote computer, you actually launch two programs: a local FTP client program: It asks the FTP server for a copy of the file. The other is the FTP server program that launches on the remote computer, and it responds to your request to transfer the files you specified to your computer.
