Window Management refers to the way operating systems handle the display and organization of multiple application windows on a computer screen. It allows users to open, close, resize, and move windows around, making it easier to multitask and access different programs simultaneously. Good window management enhances productivity by providing a clear view of all active applications. There are various techniques for effective Window Management, such as using keyboard shortcuts, virtual desktops, and snapping windows to the edges of the screen. These tools help users quickly switch between tasks and keep their workspace organized, ultimately improving their overall computing experience.
