The lines in windows are called window borders. Windows borders are the lines that separate one window from another, or the lines that border a window. They are also referred to as window frames or window edges.
Window borders are a crucial part of the Windows operating system. They provide a way for users to navigate between windows, as well as to move and resize windows. In addition, they provide a way for users to control the appearance of their windows.
Window borders are typically made up of several components. The first component is the title bar, which is the topmost part of the window. The title bar contains the name of the window as well as buttons for minimizing, maximizing, and closing the window. The second component is the menu bar, which is located just below the title bar and contains menus for accessing various functions and settings. The third component is the status bar, which is located at the bottom of the window and displays information about the current window. Finally, the fourth component is the window frame, which is the line that surrounds the window and contains the minimize, maximize, and close buttons.
Window borders can be customized in a variety of ways. Users can change the color, size, and style of the window border to suit their preferences. In addition, users can also add decorative elements, such as icons, to the window border to make it more visually appealing.
Window borders are an important part of the Windows operating system and provide a way for users to control the appearance and functionality of their windows. They are also a useful way to distinguish one window from another and to move and resize windows. By customizing the window border, users can create a unique look and feel for their windows.
