File transfer
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, numerous file transfer protocols have been designed for different contexts.
Protocols
A file transfer protocol is a convention that describes how to transfer files between two computing endpoints. As well as the stream of bits from a file stored as a single unit in a file system, some may also send relevant metadata such as the filename, file size and timestamp - and even file system permissions and file attributes.
Some examples:
- FTP is an older cross-platform file transfer protocol[1]
- SSH File Transfer Protocol a file transfer protocol secured by the Secure Shell (SSH) protocol
- Secure copy (scp) is based on the Secure Shell (SSH) protocol
- HTTP can support file transfer
- Bittorent, Gnutella and other distributed file transfers systems use peer-to-peer
- In Systems Network Architecture, LU 6.2 Connect:Direct and XCOM Data Transport are traditionally used to transfer files
- Many instant messaging or LAN messenger systems support the ability to transfer files
- Computers may transfer files to peripheral devices such as USB flash drives
- Dial-up modems null modem links used XMODEM, YMODEM, ZMODEM and similar
gollark: Ignoring things when it's convenient.
gollark: See, us humans have *amazing* abilities when it comes to ignoring things which don't directly affect us.
gollark: Anyway, you could probably make reasonable ethical arguments that I should be vegan instead of vegetarian, but I don't actually care.
gollark: The better argument, I think, is that you can't go around objectively measuring what we "should" do somehow.
gollark: That's like saying "the fact that some people believe the earth is flat is evidence enough that there is nothing objective about the eath's shape".
