DefinitionWindows is an operating system for PCs, developed and sold by Microsoft.
ExplanationIt adopted a GUI early on, letting users work with several windows on screen using a mouse, and it is widely used both at home and at work. Because it runs on PCs built by many different companies rather than a single maker, a large range of applications and peripherals support it.
AnalogyIt is like a car navigation unit built to a common standard that fits cars from any maker, so compatible parts and map software are easy to find.
Memory hookThe name is simply the plural of "window," taken from the way you stack several windows on the screen.
