Operating System
An operating system, or "OS," is software that communicates with the hardware and allows other programs to run. It is comprised of the system software, or the fundamental files your computer needs to boot up and function. Every desktop computer, tablet, and smartphone includes an operating system that provides basic functionality for the device.
Common desktop operating systems include Windows, OS X, and Linux. While each OS is different, most provide a graphical user interface, or GUI, that includes a desktop and the ability to manage files and folders. They also allow you to install and run programs written for the operating system. Windows and Linux can be installed on standard PC hardware, while OS X is designed to run on Apple systems. Therefore, the hardware you choose affects what operating system(s) you can run.
Mobile devices, such as tablets and smartphones also include operating systems that provide a GUI and can run applications. Common mobile OSs includes Android, iOS, and Windows Phone. These OSs are developed specifically for portable devices and therefore are designed around touchscreen input. While early mobile operating systems lacked many features found in desktop OSs, they now include advanced capabilities, such as the ability to run third-party apps and run multiple apps at once.
