Processor (cpu: all computations occur here, used for storage (small amount, quick, expensive) Hard-drive: several spinning platters turning on a spindle, used for storage (used if things are not in main memory, when computer is off all files are in hdd, when computer is on most files are in hdd. For cpu and ram, when power is off everything is lost. When anything is on screen, what is seen is whatever is on the ram and then can only be changed on hdd if saved.
