What is the main function of an Operating System?

The main function of an Operating System (OS) is to serve as an interface between hardware and users. This means that it acts as a mediator that enables users and application software to interact with the computer’s hardware resources efficiently. The OS manages how applications utilize hardware components such as the CPU, memory, storage devices, and input/output devices. It provides a user-friendly environment for users to execute tasks, manage files, and run applications.

This central role allows the operating system to perform vital tasks such as handling user commands, managing system resources, and ensuring that different programs and users can operate smoothly without conflicts. The OS also abstracts the complexity of hardware interactions, allowing users to operate systems without needing to understand the underlying complexities of the hardware itself. Thus, it plays an integral role in ensuring both usability and performance in computing environments.
