Hard Drive

Explanation:

A hard disk is the main memory bank of a computer. All the important files must be storaged there. But if you lose it, your computer will not remember how to do anything, and you will lose all your data. This is why protecting the hard drive is important. But most people save years worth of working on their hard drives and think nothing about protecting or saving it until it's too late. Rather than spending hours, weeks, or even months recovering from losing a hard drive, save your work and make a backup copy.
