The main function of an operating system is to manage computer hardware and provide services for programs. This encompasses several key responsibilities that enable both hardware and software to work together effectively.

An operating system serves as a bridge between the hardware components of a computer (such as the CPU, memory, and storage devices) and the user applications that require resources to operate. By managing hardware resources, the operating system allocates memory, processes tasks, handles input and output operations, and ensures that applications can execute efficiently without conflict. Additionally, it provides a user interface and system calls that applications use to perform tasks, interact with files, and manage system operations.

This extensive role is crucial for the operation of any computing device, whether it’s a desktop, laptop, or server. By overseeing these functions, the operating system ensures that the computer's various parts work together harmoniously, facilitating the execution of complex applications and allowing users to perform various tasks effectively.
