FTP Server
An FTP (File Transfer Protocol) server is a software application that enables the transfer of files between computers over a network, typically using the FTP protocol. It allows users to upload, download, and manage files on a remote server, often used for web hosting, data backup, and file sharing. FTP servers can operate in active or passive modes and support various authentication methods, including anonymous access.
Developers should learn and use FTP servers when they need to transfer files between local and remote systems, such as deploying website files to a web hosting service or managing data backups. It is particularly useful in scenarios where simple, standardized file transfer is required without the complexity of modern cloud storage solutions, though it is less secure than alternatives like SFTP or FTPS for sensitive data.
