Final answer:
FTP stands for File Transfer Protocol, which is used to transfer files between a client and server over a network. This protocol utilizes a client-server model with separate channels for control and data, enabling users to manage and transfer files if they have the required permissions.
Step-by-step explanation:
FTP stands for File Transfer Protocol. It is a standard network protocol used for the transfer of computer files between a client and server on a computer network. FTP is built on a client-server model architecture and uses separate control and data connections between the client and the server. Users who have permission to access an FTP server can upload, download, delete, and modify files on the server.
FTP operates on two distinct channels, with the control channel (usually port 21) handling the connection setup, authentication, and commands, while a separate data channel is used for the actual transfer of files. This helps maintain command communication without interfering with the file transfer. FTP can run in active or passive mode, which refers to the method of establishing the data channel.
