Drives. A computer’s drives are the devices used for long term storage of information. The main storage area for a computer is its internal hard drive (also called a hard disk). The computer should also have disk drives for some sort of removable storage media. A floppy disk drive was very common until recent years, and is still found on many older desk top computers. It was replaced by CD-ROM and DVD drives, which have higher storage capacities. The current standard is a DVD-RW drive, which can both read and write information using both CD and DVD disks. The USB ports (described later) on a computer can also be used to connect other storage devices such as flash drives and external hard drives.
