FTP is a protocol that allows transferring files between two computers. Although FTP is a protocol, it is also a program. It transfers files between two computers using FTP protocol through a program.

By connecting to the computer via FTP, we can list both folders and files and download files from our computer. To give another example of FTP usage, we can easily upload or download files by accessing the Web Server.

In short, after establishing a connection between the FTP Client and the FTP Server computers, we can make any changes to the files on the FTP Server. So, we can delete or edit these files.

Also, when transferring files via FTP, a user name and password are needed. However, in some cases, an Anonymous account can be created to set up a common public access server.

The FTP protocol uses TCP and uses 21 ports assigned by IANA by default.
