TTY: Text Terminal or Virtual Console or Virtual Terminal. A Char device created by kernel. Init will use getty (from inittab) to generate the first 6 text based terminal interfaces for console access. They receive input and display output. You can think of it as a layer b/w the program (normally shell) and your keyboard and monitor.
