What are the two types of user interfaces mentioned?

• A. Graphical and Command Line Interfaces
• B. Text-Based and Voice Interfaces
• C. Menu-Driven and Sensor Interfaces
• D. Console and GUI Interfaces

Answer: (A)

Two common ways users interact with computers are graphical user interfaces and command line interfaces. A graphical user interface uses visual elements—windows, icons, menus—and input through a mouse or touch, making tasks easy to learn and discover. A command line interface provides a text prompt where you type commands, which can be much faster and highly scriptable once you know the commands. These two form the broad spectrum of interaction: visual, interactive control versus text-based, command-driven control. The other pairings aren’t the standard two discussed. Text-based and voice interfaces mix modalities and aren’t usually presented as the two primary categories; menu-driven and sensor interfaces aren’t the typical primary division for human–computer interaction; and console interfaces are essentially a type of command line interface, not a distinct second category from graphical interfaces.
