Explanation:

A hard disk drive (HDD) is a non - volatile storage device. Its main function is to store data (including the operating system, applications, and user files) for long - term use. The operating system is controlled by software (e.g., Windows, Linux) and the CPU to some extent, not the HDD. Visual interaction with a computer is enabled by output devices like monitors. And a computer's internal parts are housed in the computer case, not specifically the HDD.

Answer:

It stores all of the information on a computer.
