S: (n) flash memory (nonvolatile storage that can be electrically erased and programmed anew)
S: (n) magnetic bubble memory (a nonvolatile storage device that holds information in the form of bubbles on a thin film of magnetic silicate; no longer used in most computers)
S: (n) CD-ROM, compact disc read-only memory (a compact disk that is used with a computer (rather than with an audio system); a large amount of digital information can be stored and accessed but it cannot be altered by the user)
S: (n) scratchpad ((computer science) a high-speed internal memory used for temporary storage of preliminary information)
S: (n) virtual memory, virtual storage ((computer science) memory created by using the hard disk to simulate additional random-access memory; the addressable storage space available to the user of a computer system in which virtual addresses are mapped into real addresses)
S: (n) random-access memory, random access memory, random memory, RAM, read/write memory (the most common computer memory which can be used by programs to perform necessary tasks while the computer is on; an integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations are equally accessible)
S: (n) magnetic core memory, core memory ((computer science) a computer memory consisting of an array of magnetic cores; now superseded by semiconductor memories)
S: (n) scheduler (computer hardware that arranges jobs to be done by the computer in an appropriate order)
S: (n) sequencer (computer hardware that sorts data or programs into a predetermined sequence)
S: (n) upgrade (hardware that provides better performance than an earlier version did)
