Telnet is the method that allows connection to a remote computer over the Internet and using programs and data as if they were on your local machine. User data is distributed in-band with Telnet control information in an 8-bit byte data connection over the TCP (Transmission Control Protocol (TCP) port number 23) where a Telnet server application (telnetd) is listening.
