File transfer is the "transmission of a "computer file through a "communication channel from one computer system to another. Typically, file transfer is mediated by a "communications protocol. In the "history of computing, a large number of "file transfer protocols have been designed for different contexts.
Some examples of file transfer:
A file transfer protocol is a convention that describes how to transfer files between two computing endpoints. They are meant solely to send the stream of "bits stored as a single unit in a "file system, plus any relevant "metadata such as the "filename, file size and "timestamp.
File transfer protocols usually operate on top of a lower-level protocol in a "protocol stack. For example, the HTTP protocol operates at the topmost application layer of the "TCP/IP stack, whereas "XMODEM, "YMODEM, and "ZMODEM typically operate across "RS-232 serial connections.
