The client then can issue further FTP commands or disconnect from the server.

When the file transfer is complete, the data connection is closed.

The data connection transfers the actual file contents between the client and the server. For file transfers, the client opens a separate data connection to the server.The client can then issue FTP commands, such as upload, download, delete, or list files, to the server.Sometimes, anonymous access is also possible.

If the authentication is successful, the server grants access to the client.

The client authenticates with the server by providing a username and password.

The server responds with a message indicating that the connection has been established.

A client establishes a connection to the FTP server by requesting the server’s IP address and port number.

Now that you know the details, let’s see how it all comes together: For example, you may need to change the ports if you are running multiple FTP servers on the same machine and want to avoid port conflicts or if you want to customize the port numbers for security or other reasons. However, changing the ports used by FTP, if necessary, is possible. The default ports for FTP (port 21 for the command connection and port 20 for the data connection) are standardized and widely used, so it is generally recommended to use these ports for FTP. When a client uses the control connection to “ask” an FTP server to transfer a file, this channel sends the said file. This is the channel through which an FTP server exchanges file listings and transfers files. The second type of connection is called the data connection. Its ultimate purpose is to enable clients to connect and send commands to the server as well as receive server responses. The control connection is always the first connection established with an FTP server. The protocol uses separate control (command) and data connections between the client and the server. How FTP works ( Source: GeeksforGeeks)įTP is built on a client-server model architecture. TCP establishes a connection between two devices, divides the data into segments, and sends the segments to the destination device, where they are reassembled into the original data stream. Now that we’ve answered, “What is FTP?” let’s learn how it works.įTP uses and relies on Transmission Control Protocol (TCP) to ensure all the data packets are sent correctly and to the proper destination.

For example, if you want to update your WordPress website, you can use FTP to upload files to the host server directly, which is fast and effective. Now, there are at least three variations of the protocol - we’ll talk about them in more detail in the following sections.įTP isn’t some niche technology for geeks - it’s commonly used by website owners worldwide. FTP has since undergone several revisions in attempts to make it more secure.

The protocol was first developed in 1971 by Abhay Bhushan Pandey, a student at the Massachusetts Institute of Technology. FTP can also be used to upload files from a computer to a web hosting account. FTP is useful for transferring files between computers, either remotely or within a local network - your personal computer can even act as an FTP server. This communication protocol is used for file exchange between a server and a client. Check Out Our Video Guide on File Transfer Protocol (FTP): What Is FTP?įTP stands for File Transfer Protocol.
