Virtually all desktop computers and most other types of computers have a hard drive or hard disk drive. Some have more than one. Any device, from video recorders to cell phones, may have hard drives. These devices have one important task. They store the information on your computer. All of the changes in your computer on a daily basis, even a minute by minute basis, are stored on the hard drive.
