'''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 field|magnetic fields]].

A '''Hard disk''' drive is a form of [[computer]] memory consisting of spinning magnetic platters inside a sealed case.<ref>[https://www.britannica.com/technology/hard-disk Hard disk] from britannica.com</ref> [[Magnetism|Magnetization]] is used to store compartmentalized information in [[binary]] code, by spinning the hard disks (called platters) of the drive past read/write heads, which set small points (which represent [[Bit (computer)|bits]]) to a north or south polarity. A single hard disk will contain billions of these individual points of information, which are aggregated to form larger incraments of storage, such as [[byte]]s or megabytes.  Hard disks are vulnerable to [[magnetic field]]s, although they are encased in metal, so the platters themselves are somewhat protected.
