A graphical user interface (GUI) is a visual way of interacting with an operating system or application, using icons, menus, and other visual elements to control and navigate the software. The GUI is typically displayed on a monitor or screen, allowing users to interact with the computer in a more intuitive and user-friendly manner. The main components of a GUI include: Windows: These are rectangular frames that contain various GUI elements, such as buttons, menus, and text boxes. Icons: Small images used to represent files, folders, or applications. Menus: Drop-down lists of options that allow users to perform specific tasks or access certain features. Dialog boxes: Small windows that pop up to request user input or display important information. Toolbars: Horizontal or vertical bars at the top or bottom of a window that contain frequently used commands or functions.
