FTP (File Transfer Protocol) is a standard communication protocol used to transfer files between computers over a TCP/IP network, such as the Internet. It allows users to upload files from a local computer to a remote server, download files from a server, and perform file management operations such as renaming, deleting, moving, and creating directories. FTP is commonly used by web developers and website administrators to upload website files to a web hosting server. It operates on a client-server model, where an FTP client connects to an FTP server using valid login credentials or anonymous access if permitted.
FTP typically uses Port 21 for establishing the control connection and Port 20 for transferring data in active mode. Modern FTP clients such as FileZilla and WinSCP provide a graphical interface that makes file transfers simple and efficient. Since standard FTP does not encrypt data, secure alternatives like FTPS (FTP Secure) and SFTP (SSH File Transfer Protocol) are preferred for transferring sensitive information over the Internet.
Why the other options are incorrect:
- File Transfer Post is not a recognized computer networking term or protocol.
- File Transit Protocol is not an official Internet protocol defined by networking standards.
- None of these is incorrect because File Transfer Protocol is the correct and universally accepted expansion of FTP.
