A tty (teletypewriter) is a Unix command that prints to standard output the name of the terminal connected to standard input. It is typically called a terminal.

Also, tty's are very useful when the user needs to install additional drivers (such as the Nvidia or AMD ones), troubleshoot X11 problems and/or doesn't need to use a GUI.
