The SCP is a network protocol, based on the BSD RCP protocol, [5] which supports file transfers between hosts on a network. SCP uses Secure Shell (SSH) for data transfer and uses the same mechanisms for authentication, thereby ensuring the authenticity and confidentiality of the data in transit.
WinSCP (Windows Secure Copy) [3] is a file manager, SSH File Transfer Protocol (SFTP), File Transfer Protocol (FTP), WebDAV, Amazon S3, and secure copy protocol (SCP) client for Microsoft Windows. The WinSCP project has released its source code on GitHub under an open source license, while the program itself is distributed as proprietary ...
A packet-switched network transmits data that is divided into units called packets.A packet comprises a header (which describes the packet) and a payload (the data). The Internet is a packet-switched network, and most of the protocols in this list are designed for its protocol stack, the IP protocol suite.
Compared to the SCP protocol, which only allows file transfers, the SFTP protocol allows for a range of operations on remote files which make it more like a remote file system protocol. An SFTP client 's extra capabilities include resuming interrupted transfers, directory listings, and remote file removal. [ 2 ]
It also supports mechanisms for tunneling, forwarding of TCP ports and X11 connections and it can be used to transfer files using the associated SSH File Transfer Protocol (SFTP) or Secure Copy Protocol (SCP). [3] SSH uses the client–server model.
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; BitTorrent, Gnutella and other distributed file transfers systems use peer-to-peer
While uploading can also be defined in the context of sending files between distributed clients, such as with a peer-to-peer (P2P) file-sharing protocol like BitTorrent, the term file sharing is more often used in this case. Moving files within a computer system, as opposed to over a network, is called file copying.
The File Transfer Protocol was drafted in 1971 for use with the scientific and research network, ARPANET. [1] Access to the ARPANET during this time was limited to a small number of military sites and universities and a narrow community of users who could operate without data security and privacy requirements within the protocol.
