☆ Hard Disk ☆
A hard disk drive contains disks made of metal and coated with a metal oxide that can be magnetized. It is used to store lots of programs and data. You can see this from outside but it can store more information than a floppy disk. Hard drives are rated by their storage capacity, typically tens or hundreds of gigabytes. They are also rated by how fast the disks spin (in rpm, rotations ler minute), which is typically thousands of rpm.
When we purchase a computer, it has hard disk, which is called Drive C: and is placed inside the computer case (CPU).
The information or the data are permanent on the Hard Disk, until you erase it.
