Which of the following best describes a GUI?

A graphical user interface (GUI) is characterized by its use of graphical elements such as windows, icons, buttons, and menus to facilitate user interaction with a computer or software application. This approach contrasts with text-based interactions, where users input commands through text alone. In a GUI, users can manipulate these graphical elements with a mouse or touch gestures, making the experience more intuitive and user-friendly. This method greatly enhances the accessibility of software to those who may not be familiar with coding or command line interfaces.

The other options define concepts that are not related to GUIs. Text-based interactions refer to command line interfaces, which rely on text input. Database management software focuses on organizing and managing data rather than providing an interactive interface. Network programming protocols deal with communication between computers and devices over networks, which is unrelated to user interface design. Thus, option B accurately captures the essence of what a GUI is and how it operates in user interactions.
