What does GUI stand for?

The term GUI stands for Graphical User Interface. This concept refers to the visual elements of a computer system that allow users to interact with the software and hardware using graphical icons, buttons, and other visual indicators, as opposed to text-based interfaces. A Graphical User Interface enhances usability by making it easier for users to navigate and control computer systems through visual representations, which can be more intuitive than command-line interfaces that require knowledge of specific commands.

The other options do not accurately capture the established definition of GUI. For instance, "General User Interface" misrepresents the specific nature and focus of GUIs, while "Graphical Unified Interface" introduces the term "unified" in a way that doesn't reflect the actual terminology used in the field. Lastly, "General Unified Interface" lacks both the correct focus on graphical elements and the precise terminology recognized in IT contexts.
