What is the main function of an operating system?

To manage applications
To manage hardware resources
To provide an interface between the user and the computer
To execute programs

The correct answer is: To manage hardware resources

An operating system manages the hardware resources of a computer, such as memory, storage, and processing power. A is incorrect because an operating system does not manage applications, it simply allows them to run on the hardware. C is incorrect because while an operating system does provide an interface for the user to interact with the computer, this is not its main function. D is incorrect because an operating system does not actually execute programs, it directs the hardware to execute them.
