Main functions of operating systems are
To provide user interface
To manage resources
To run applications
"An operating system is the most important software that runs on a computer. It manages the computer's memory and processes [resources], as well as all of its software and hardware [like running applications]. It also allows you to communicate with the computer without knowing how to speak the computer's language [interface]. Without an operating system, a computer is useless."
