getty, short for "get teletype", is a Unix program running on a host computer that manages physical or virtual terminals (TTYs). When it detects a connection, it prompts for a username and runs the 'login' program to authenticate the user. It is usually called by init.
Originally, on traditional Unix systems, getty handled connections to serial terminals (often teletype machines) connected to a host computer. The tty part of the name stands for teletype, but has come to mean any type of text terminal. One getty process serves one terminal. In some systems, for example, Solaris, getty was replaced by ttymon.
