A modem only transmits the data, the computer uses a protocol to connect to the ISP. Different types of protocol exist, but I think you're probably thinking of FTP - File Transfer Protocol.
If the modem is used to connect to an ISP for an internet connection, than the standard internet protocols and utilities can be used for file transfer. They include ftp, sftp, http and the wget command. If the modem is used to establish a serial connection such as a terminal emulation session, protocols like kermit and xmodem/ymodem/zmodem should be available that perform errorfree file transfers.
File Transfer Protocol, also known as FTP.
File transfer protocol OR FTP
SFTP is a network protocol that gives access to files, transfer of files, and the management function of files over reliable streams of data. SSH File Transfer Protocol was designed by the Internet Engineering Task Force as an extension of the Secure Shell protocol version 2.0 to give files a secure transfer capability.
There are numerous advantages of file transfer protocol and one of it is the capability to transfer big chunks of files from one unit to another. Also, with file transfer protocol, data is being transferred back and forth through a same server from both sides.
WebDAV uses HTTP over TCP to transfer files.
Because it was designed that way.. FTP is an acronym for File Transfer Protocol SFTP is the secure version..
A set of rules used for transferring data over the Internet is called a "protocol".Hypertext transfer protocol, HTTP.
File transfer protocol
The File Transfer Protocol (FTP) allows a user to transfer files over a local network or the Internet, as well as allowing browsing of folders on an FTP server. While it is possible to transfer files using HTTP, FTP is more efficient and allows for features not found in HTTP file transfers, like authentication for accessing certain files.
FTP. (Perhaps you would like to clarify your question and try again, because FTP is a protocol; it stands for File Transfer Protocol.)
FTP uses TCP.Usage of Transport Layer protocol (tcp or udp) depends upon various applications.Such as FTP uses TCP, TFTP uses UDP.
It is file transfer protocol, As a send the file inside the network, One of the oldest of the interner services, file transfer protocol makes it possible to move one or more files securely between computers while providing file security ans organization as well as transfer control.
