Which statement describes a Command Line Interface?

• A. Graphical interface with icons and windows.
• B. Voice-based assistant.
• C. Direct hardware control panel.
• D. Entirely text-based interface that allows a user to communicate with a computer system by typing in commands.

Answer: (D)

A Command Line Interface is an entirely text-based way to interact with a computer by typing commands at a prompt. You don’t use icons or windows; instead, you enter text commands and the system responds with text. This style is common for tasks like file navigation, program execution, and automation through scripts, because commands can be combined and reused easily. The other descriptions fit different ways humans interact with computers: a graphical interface uses icons and windows, a voice-based assistant relies on spoken language, and a hardware control panel refers to physical controls rather than a software-driven text interface.
