An FTP server is a computer that stores files and makes them available to other users over a network. FTP stands for File Transfer Protocol, and it is a standard protocol for transferring files between computers.

FTP servers are used for a variety of purposes, including:

• Sharing files between different computers or devices
• Transferring files to and from a web server
• Backing up files to a remote server
• Distributing software updates or other files to a large number of users

To use an FTP server, you need to have an FTP client program. FTP client programs are available for a variety of platforms, including Windows, macOS, Linux, and mobile devices.

Once you have an FTP client program, you can connect to an FTP server by entering the server’s address and login credentials. Once you are connected, you can browse through the files on the server and download or upload files as needed.

FTP servers are a convenient and efficient way to transfer files between computers. They are also relatively easy to use, even for users who are not familiar with networking or file transfer protocols.
