This magnetic storage method is what allows for the long-term retention of data on a hard drive.
18.
If media is damaged by water, first __
Correct Answer
C. Dry it
Explanation
If media is damaged by water, the first step should be to dry it. This is because water can cause damage to electronic components and circuits, leading to malfunction or complete failure. By drying the media, the moisture is removed, reducing the risk of further damage and increasing the chances of it functioning properly again. Restarting the computer or placing it in an airtight plastic bag may not effectively address the water damage issue, whereas drying it directly targets the problem. Therefore, drying the media is the most appropriate course of action in this situation.
