What is FTP?
File Transfer Protocol (FTP) is a standard network protocol used for the transfer of files from one host to another over a Wide Area Network (WAN), such as the Internet. FTP is a client-server protocol, meaning that a client establishes a connection to the server in order to access files.
The protocol was first defined in 1971 and has since undergone several upgrades and modifications. FTP is a widely-used transfer protocol that supports a range of file formats, including text, images, audio, and video files.
FTP typically uses two channels to transfer data: one for data transfer and the other for control. For example, before a file transfer can occur, the client must establish a connection with the server through a control channel. Once the connection is established, the client sends a request to transfer the file, and the server responds by opening a data channel. The data channel allows the transfer of the actual file.
Some of the notable features of FTP include support for remote access and authentication, as well as the ability to resume transfers in case of failure. FTP also supports several file management operations, such as renaming and deleting files.
Telnet vs. FTP Protocol Comparison
