1 GiB of SDRAM mounted in a personal computer. An example of primary storage. | | GiB | SDRAM | personal computer | 40 GB hard disk drive (HDD); when connected to a computer it serves as secondary storage. | | GB | 160 GB SDLT tape cartridge, an example of off-line storage.  When used within a robotic tape library, it is classified as tertiary storage instead. | | SDLT | tape library | computer | recording media | data | central processing unit | semiconductor | random access memory | mass storage | optical discs | magnetic storage | hard disks | digital computer | datum | binary numeral system | bits | byte | data | megabyte | central processing unit | calculators | digital signal processors | Von Neumann | instructions | reprogrammed | state | storage hierarchy | bandwidth | latency | Various forms of storage, divided according to their distance from the central processing unit.
