The type of interface that requires the user to type in commands is the Command-line Interface (CLI). This interface allows users to interact with the computer or software by typing specific commands at a prompt, which the system interprets and executes. It is known for its efficiency, particularly for experienced users who can quickly navigate and perform complex tasks through precise command inputs.

In contrast, a Graphical User Interface (GUI) utilizes graphical elements like windows, icons, and menus, allowing users to interact using a mouse or touch gestures rather than text commands. Touch interfaces are designed for direct interaction with screen objects via touch gestures, suitable for tablets and smartphones. Voice User Interfaces (VUIs) enable interaction through spoken commands, making them accessible for hands-free control.

The nature of command-entry in a Command-line Interface emphasizes precision and familiarity with specific commands, distinguishing it from the other types of interfaces that rely on visual or auditory input.
