A computer's hard disk or hard drive stores information such has the operating system, programs, and files. It stores the information as small magnetic fields on the hard disc.
A hard disk drive is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid (i.e. hard) platters with magnetic surfaces.
