File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the Internet. It allows users to upload, download, and manage files on remote servers, making it essential for web development and data sharing. FTP operates on a client-server model, where the client initiates a connection to the server to request file transfers. It supports various authentication methods and can operate in two modes: active and passive. This flexibility makes FTP a widely used tool for both individuals and organizations.
