A File Transfer Protocol (FTP) is a standard network protocol used for transmitting files between computers on the internet. Any two computers that are on the same network (and that can be on the Internet) can transfer files using the File Transfer Protocol. There's an application in there, known as "ftp," that directs the actual protocol (FTP) to transfer files. Here's how it works:
Here is what file transfer protocol can do:
You can count on FTP to deliver files cleanly. Attaching large files in an email can fail at times—as you've probably experienced—or it can freeze up a computer for long stretches of time.
Because FTP uses the TCP (networking) protocol, it operates through a reliable connection as a transfer "session" between the client (host) and server (remote) computers.
In addition to allowing you to send large files that would crash as an email attachment, FTP typically lets you see, with certainty, that a file is on the server, and it lets you know if and when the transferred file reached its destination.
