Define window border

Answer 1

One is a visual border in a document, sometimes a solid line, dotted or dashed line, or one made up of various objects, like flowers, baseballs, animals or virtually any other object. These borders can be used to represent the outer edge of a document or separate sections within a document from each other.

Answer 2

In graphical user interfaces, the window decoration is a part of a window in most windowing systems. A windows decoration typically consists of a title bar, usually along the top of each window and a minimal border around the other three sides. On Microsoft Windows this is called "nonclient area".
