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." 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.
