The first and most important storage device

1. The hard disk inside your computer is the biggest and most important storage device. It is like a filling cabinet¹, but instead of paper cards, it saves everything electronically.

2. It can hold all the software you have on your computer and all your files.

3. A hard disk normally contains a few disks which are stacked on top each other. There are five or more in many computers.

4. The drive motor spins the disks very quickly. It runs all the time while your computer is in use.

5. There is a gap, a space between disks. The computer needs gaps, so that read/write heads can move across the disks and reach all the parts of disks very quickly. The head motor controls the read/write heads.

6. The space between the head and the disk surface is tiny. Even smoke from cigarette can cause a crash. A crash is what happens when the head touches the surface of the disk. To keep out dust and smoke, the drive disk is inside a sealed case.

Note: 1 – каталожный ящик.
