Terminal (Terminal.app) is the terminal emulator included in the OS X operating system by Apple Inc..[1]

Terminal originated in NeXTSTEP and OPENSTEP, the predecessor operating systems of OS X.

As a terminal emulator, the application provides text-based access to the operating system, in contrast to the mostly graphical nature of the user experience of OS X, by providing a command line interface to the operating system when used in conjunction with a Unix shell, such as bash.

The preferences dialog for Terminal.app in OS X 10.8 (Mountain Lion) offers choices for values of the TERM environment variable. Available options are ansi, dtterm, nsterm, rxvt, vt52, vt100, vt102, xterm, xterm-16color and xterm-256color, which differ from the OS X 10.5 (Leopard) choices by dropping the xterm-color and adding xterm-16color and xterm-256color. These settings do not alter the operation of Terminal, and the xterm settings do not match the behavior of xterm.[2]

Terminal.app features include tabs and customization of fonts and colors.

The defaults command is often used to set hidden settings via the shell and is only found in Nextstep-derived systems like OS X.
