What is the difference between a frame and a panel?

Answer: The key differences between a frame and a panel in a GUI are as follows: 1. Purpose: A frame serves as the primary container for an application's user interface, while a panel divides and organizes components within a frame. 2. Hierarchy: A frame is at the top level in a GUI application and is part of the main window, while a panel is a nested container within a frame. 3. Components: Frames can hold panels and other components directly, whereas panels must be placed within a frame or another container to be displayed. 4. Window controls: Frames typically have window controls such as minimize, maximize, and close buttons, while panels do not have these controls. 5. Independency: Frames are independent containers that can exist on their own without being nested in another container, whereas panels must be part of a frame or another container.
