The most widely used operating system for desktop and laptop computers. Developed by Microsoft, Windows primarily runs on x86-based computers (the ubiquitous PC), although versions have run on Intel's Itanium CPUs. Windows provides a graphical user interface and desktop environment in which applications are displayed in resizable, movable windows on screen.
Windows comes in both client and server versions, all of which support networking, the difference being that the server architecture is designed for dedicated server hardware. Although they can easily share their data with other users on the network, the client versions of Windows are geared to running user applications. While Windows is the dominant desktop OS, Linux is the leading server OS. See Linux, operating system, smartphone operating system and embedded OS.
