== File Transfer Protocol (FTP) ==

The '''File Transfer Protocol''' (FTP) is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP operates over the [[Transmission Control Protocol]] (TCP) or, in some cases, over the [[User Datagram Protocol]] (UDP). Typically, FTP operates on port 21 for control connections and port 20 for data connections.

=== Operation ===

FTP allows users to upload and download files from a server. It provides commands to navigate directories, list files, upload and download files, and perform other file operations.

=== Security ===

FTP originally lacked security features, transmitting data in plain text, including usernames, passwords, and file contents. However, secure variants of FTP have been developed, such as FTPS ([[FTP Secure]]) and SFTP ([[SSH File Transfer Protocol]]), which encrypt the data during transmission, providing confidentiality and integrity.

=== Advantages ===

* FTP is widely supported by most operating systems and network devices.
* It allows for the transfer of large files efficiently.

=== Disadvantages ===

* FTP does not natively support encryption, making it vulnerable to eavesdropping and data tampering.
* It requires a separate port for data transfer, which can complicate firewall configurations.

=== Alternatives ===

Alternative protocols for file transfer include [[Secure_Shell|SSH File Transfer Protocol (SFTP)]], which provides encrypted file transfer capabilities over an SSH connection, and [[File_Transfer_Protocol#FTPS|FTP Secure (FTPS)]], which adds encryption to the FTP protocol.
