The hard disk drive in your system is the "data center" of the PC. It is here that all of your programs and data are stored for future retrieval. Your hard disk (or disks) is the most important category of permanent storage used in PCs (the others being floppy disks and other storage media such as CD-ROMs, tapes, removable drives, etc.) The hard disk differs from the other types primarily in three ways: size (usually larger), speed (usually faster) and portability (usually fixed in the PC and not removable).
