What are all the elements that are displayed on a computer screen collectively referred to as?

The correct term for all the elements displayed on a computer screen is the User Interface. This refers to the overall means by which a user interacts with a computer system, encompassing everything that the user can see and interact with, such as menus, buttons, text, icons, and other visual components.

A well-designed user interface allows for seamless navigation and enhances user experience by making it intuitive to interact with the software or operating system. While terms like "Screen Components," "Display Elements," and "Graphical User Interface" are commonly used in discussions about user interfaces, they do not capture the full scope of what the user interface entails. "Screen Components" might refer to individual parts of the display, while "Display Elements" is an informal term that does not cover the inclusive functionality of the interface. The term "Graphical User Interface" is more specific to interfaces that primarily use graphical elements, but again, it does not encompass all potential interactions. So, User Interface is the most accurate way to describe the collective elements displayed on a screen that facilitate interaction.
