Terminal is the built in terminal emulator that is default on Apple computers.
Terminal grants the user access to the Command Line Interface (CLI) of macOS. Written in C and Objective C, terminal has been developed to be highly customizable. Users can chose to use a variety of different shells in terminal, and can customize terminals look and feel in

Terminal users have access to special commands that interact with the macOS API’s, as well as familiar unix commands.
