A windowing system is a software framework that allows multiple applications to run simultaneously on a computer screen. It manages the display of different windows, enabling users to interact with various programs without closing them. This system provides features like resizing, minimizing, and moving windows, enhancing user experience and productivity. Most modern operating systems, such as Windows, macOS, and Linux, incorporate windowing systems. They use graphical user interfaces (GUIs) to present information visually, making it easier for users to navigate and manage their tasks. The windowing system is essential for multitasking and efficient use of screen space.
