Question

what does an operating system do?
a. it allows the computer to start up and function
b. it keeps the computer from using application software.
c. it tells the computer user how to operate the computer.
d. it operates the mouse, but not the other hardware.

Explanation:

An operating system is software that manages computer hardware and software resources. It enables the computer to start up (boot) and function by providing a platform for running applications, managing memory, handling input/output operations, etc.

• Option B is incorrect as the operating system is used to run application software, not prevent it.
• Option C is wrong because it's not the job of the OS to directly tell the user how to operate (though it may have some user - friendly interfaces, that's not its main function).
• Option D is incorrect as the OS manages all hardware resources, not just the mouse.

Answer:

A. It allows the computer to start up and function
