Hard disks are magnetized modules of computer memory. Magnetization is used to store compartmentalized information in binary code, by turning the magnetized piece of the drive "on" or "off." The magnets become hard, very hard. Then they form disks. Then the information can be on the teh internets, or tubes. A single hard disk will contain billions of these individual points of information (bits) aggregating to larger amounts of storage, such as (bytes) or megabytes. Hard disks are vulnerable to magnetic fields.
