Final answer:
CLI operating systems require a keyboard for command input.
Explanation:
Command-Line Interface (CLI) is the type of operating system that requires a keyboard to issue commands. Unlike Graphical User Interface (GUI), CLI relies on text-based commands inputted via a keyboard.
For example, when using the Terminal application on Linux or OS X, users interact with the CLI by typing commands to perform actions.
Keyboard input is essential in CLI environments to navigate, execute commands, and interact with the shell.
