FTP includes many commands however only few are used to retrieve a file. A user is required to understand the three basic commands to connect to remote computer, retrieve a copy of file and exit FTP program. Commands with their meanings are:

Command Purpose

get                   retrieve a file from the computer

bye                  terminate the connection and leave the FTP program

Transferring a file via FTP requires at least two participants: an FTP client program and FTP server program. FTP client is the program that we run on our computers. FTP server is program that runs on huge mainframe somewhere and stores tens thousands of files. It is similar to an online library of files. FTP client can download (receive) or upload (send) files to FTP server. Using Web browser you can download the files however you can't upload the files. FTP applications will help you to upload files to the web sites, which you are maintaining.
