Telnet allows users to access and control remote computers over a network. It provides a virtual terminal that emulates a computer keyboard and display, allowing users to input commands and see outputs as if they were directly using the remote machine. To use Telnet, one needs the Internet address of the host computer they want to access, and it works by establishing a connection between the user's Telnet client program and that remote host.
