What is the main function of an Operating System?

The main function of an Operating System (OS) is to support the basic functions of a computer device. The OS acts as an intermediary between the hardware and the user applications, managing hardware resources such as the CPU, memory, storage, and input/output devices. It handles tasks such as process management, memory management, file management, and device management, ensuring that these resources are allocated efficiently and securely.

An OS provides a foundation on which applications can run and facilitates user interactions with the computer hardware. While aspects such as enhancing graphics quality, providing internet connectivity, or managing user accounts can be components of an operating system’s functionality, they are not its primary purpose. The core role of an operating system is to ensure that all components of the computer system work together effectively, allowing users and applications to utilize the hardware resources seamlessly.
