Going Further
We have just seen the use of telnet to implement the TCP/IP
protocol and allow remote logins to computers over networks.
Now we'll look at another useful TCP/IP protocol. This one
is not concerned with letting us log into a remote computer,
but with allowing us to transfer files between two different
computers on the Internet. It is named "File Transfer
Protocol", but is usually just called FTP.
The File Transfer Protocol was the standard means for transfer
of files on the Internet before the advent of the Hypertext
Transfer Protocol (HTTP) and the World Wide Web. Although
many of its functions have been taken over by the HTTP protocol,
FTP is still used extensively for file transfer on the Internet.
We shall illustrate the FTP protocol using a shareware
program called ws_ftp. We will see how WS_FTP can be used
to retrieve files from many different sources on the Internet.
