FTP (File Transfer Protocol) is a standard network protocol used to transfer files between a client and a server over a network. It allows users to upload, download, rename, and delete files on a remote system. FTP operates using a client–server model and typically uses separate channels for commands and data transfer. This protocol has been widely used for managing files on web servers and internal networks. FTP supports both anonymous and authenticated access depending on server configuration. Despite being an older protocol, FTP is still commonly found in many environments.
Using FTP can be done through command-line tools or dedicated FTP client applications. Users connect to an FTP server by providing its address along with a username and password if required. Once connected, basic commands are used to navigate directories and transfer files. The primary function of FTP is to simplify file sharing between different systems. It is especially useful for website maintenance, data backup, and large file transfers. However, because FTP does not encrypt data by default, it is often replaced by more secure alternatives in modern networks.
