FTP
FTP (File Transfer Protocol) is a standard network protocol used for transferring files between a client and server over a TCP-based network, such as the internet. It operates on a client-server model, allowing users to upload, download, delete, and manage files on remote systems. FTP supports both anonymous and authenticated access, with separate control and data connections for commands and file transfers.
Developers should learn FTP for scenarios involving manual file transfers, such as deploying web applications to hosting servers, managing content on legacy systems, or exchanging large files in environments where more modern protocols are unavailable. It remains relevant for tasks like automated backups, batch processing, and integration with older enterprise systems that rely on FTP for data exchange, though it should be used cautiously due to security limitations.
