What is the primary purpose of an operating system (OS)?

Manage user interface and computer resources
Run applications solely
Provide internet connectivity
Install hardware components

The correct answer is: Manage user interface and computer resources

The primary purpose of an operating system (OS) is to manage both the user interface and the computer's resources. An operating system acts as an intermediary between the hardware and the users, enabling users to interact effectively with the computer. It manages hardware components such as the CPU, memory, storage, and peripherals, ensuring efficient operation and resource allocation. This includes scheduling tasks, managing system memory, facilitating communication between hardware and software, and providing a user interface for easier interaction. While running applications is an essential function of the OS, it encompasses a broader role that includes resource management and user interface control. Similarly, providing internet connectivity is a service that may be facilitated by the OS, but it is not its primary function. Installing hardware components is not a role of the OS; installation is generally part of the system setup and may require other tools or software for drivers and configurations. Thus, the correct choice captures the comprehensive management functions that an OS is designed to perform.
