Understanding How FTP Works
Data exchange has been important from the early days of computing. A popular means of data exchange is connecting computers to one another.
The File Transfer Protocol (FTP) is used to transfer files between two computers over a network and Internet. In this article we will look at how to work with a FTP client. There are good FTP software in the market by which an advanced FTP client that automates file transfers between your computer and the FTP server.
What is FTP?
When you want to copy files between two computers that are on the same local network, often you can simply "share" a drive or folder, and copy the files the same way you would copy files from one place to another on your own PC.
FTP and Internet Connections
FTP uses one connection for commands and the other for sending and receiving data. FTP has a standard port number on which the FTP server "listens" for connections. A port is a "logical connection point" for communicating using the Internet Protocol (IP). The standard port number used by FTP servers is 21 and is used only for sending commands. Since port 21 is used exclusively for sending commands, this port is referred to as a command port. For example, to get a list of folders and files present on the FTP server, the FTP Client issues a "LIST" command. The FTP server then sends a list of all folders and files back to the FTP Client. So what about the internet connection used to send and receive data? The port that is used for transferring data is referred to as a data port. The number of the data port will vary depending on the "mode" of the connection.
