Windows
A window is a visible range, and each window is considered an independent execution terminal. A window can usually contain text and images. Generally speaking, in order to improve the usability of a window, a window usually contains various control components, such as a scroll bar, a title bar, and components for resizing and zooming functions. When two or more windows appear on the desktop at the same time, users can choose to overlap, side by side, or connect them according to their personal needs
