Radio

In computer science, „Radio“ often refers to a radio button, which is a GUI (Graphical User Interface) element that allows users to select one option from a set of predefined choices. Radio buttons are presented as small circles, and when one is selected, any previously selected option in the same group is automatically deselected, ensuring that only one option can be active at a time. This control is commonly used in forms and surveys where mutually exclusive options are needed, such as „Yes“ or „No“ questions, or selecting a single item from a list of options. Radio buttons enhance user interaction by providing a clear and straightforward way of making selections.
