Praxis Computer Sciences (5652) Practice Test

Which statement best describes a hard drive?

A device that processes video graphics. Temporary memory used during processing. Permanent storage on a computer. A peripheral input device.

Correct Answer:

Permanent storage on a computer.

Explanation:

Hard drives serve as long-term, non-volatile storage in a computer. They keep your files, programs, and the operating system even when the power is off, which is what makes them permanent storage. This is different from RAM, which is temporary memory used during processing and is cleared when the computer shuts down. A device that processes video graphics is a GPU, not storage. An input device like a keyboard or mouse allows you to interact with the computer, but it doesn’t store data long-term.
