An operating system is like the boss of your computer or mobile device. It manages all the different parts of your device, such as the screen, keyboard, memory and storage and makes sure they work together properly. The operating system also runs other programs and applications, such as web browsers, games and word processors. It provides a way for you to interact with your device, such as by clicking on icons or typing on a keyboard and allows you to save and retrieve files from storage. Just like a boss delegates tasks to employees, an operating system handles the tasks and resources of your device, making it possible for you to use your device the way you want.
