Which operating system (OS) user interface uses the least amount of random access memory (RAM) and central processing unit (CPU) power?

• A. Graphical user interface (GUI)
• B. Command-line interface
• C. Menu-driven interface
• D. Point-to-point interface

Answer: (B)

The command-line interface is designed to be lightweight, using significantly less random access memory (RAM) and central processing unit (CPU) power compared to other interfaces like graphical user interfaces (GUIs) or menu-driven interfaces. A command-line interface operates by receiving text commands from the user, which are processed by the operating system without the need for graphical elements, images, or animations. This minimalist approach means that fewer system resources are consumed. In contrast, graphical user interfaces incorporate visual elements such as windows, icons, and menus, which require more memory and processing power to render and manage. Menu-driven interfaces may also involve graphical components or additional complexity that can similarly increase resource use. Point-to-point interfaces can vary widely in design and functionality, but they are typically not as resource-efficient as command-line interfaces. Thus, the command-line interface stands out as the most efficient option in terms of resource utilization, making it the correct choice for this question.
