TELNET used protocol for data connection

TELNET, which stands for “Telecommunication Network,” is a protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communication facility using a virtual terminal connection. Users can connect to a remote host or server and execute commands as if they are physically present at the terminal. TELNET is based on a client-server model and operates primarily over TCP/IP on port 23. However, it is important to note that TELNET transmits data, including login credentials, in plain text, which can be intercepted and read by potential attackers. Thus, it is now largely replaced by more secure protocols like SSH (Secure Shell) for remote access needs.
