Telnet
The virtual terminal protocol in the Internet suite of protocols. It lets
users on one host access another host and work as terminal users of
that remote host. Instead of dialing into the computer, the user
connects to it over the Internet using Telnet. When issuing a Telnet
session, it connects to the Telnet host and logs in. The connection
enables the user to work with the remote machine as though a
terminal was connected to it.
