Why do we need it?
In: Technology
The operating system is a computer program that is run immediately on startup of your computer. It controls all other programs that run on a computer. The OS allows your computer to do things like run multiple programs at the same time and read/write files. It also might include drivers that allow playing audio, taking input from a keyboard, and displaying things on the screen. Many popular OSes also include a user interface, like windows and navigation. For mobile operating systems, the equivalent would be the home screen, app management, and swipe controls.
