Telnet is a network protocol used to provide bidirectional interactive text communication over a virtual terminal connection using TCP. It allows users to connect to remote hosts and access operating system command line interfaces. While once commonly used, telnet is now less favored for security reasons, replaced by more secure protocols like SSH for remote access. Most network equipment and operating systems still support a telnet service for remote configuration via telnet clients available on many platforms.
