A mechanism for interacting with a computer operating system or software by typing commands to perform specific tasks

A terminal is an interactive text-mode or text-based user interface to a software application or operating system. It may be implemented as a character-mode application or embedded in a graphical user interface.

A terminal may be used as the main user interface or as a secondary interface for debugging and administrative tasks. The degree of interactivity varies widely between terminals.

A console is a particular type of terminal, usually a physical terminal or a terminal implemented directly by the kernel. The term "console" is often incorrectly used in place of "terminal".
