What is a Button?

• A. Icon that you click to execute commands you need to work with an app
• B. A label used to describe a function
• C. A type of input device
• D. A software update

Answer: (A)

A button is an interactive control in a software interface that you click or tap to perform an action. It exists to execute commands you want the app to carry out, like saving, deleting, or opening a menu. Buttons can appear as icons, text, or a combination, and they respond to user input such as a mouse click or a touch. They’re not merely labels describing a function, which would be static text. They’re not physical input devices like keyboards or mice, and they’re not software updates. So the idea that best fits is an icon or control that you click to execute commands you need to work with an app.
