At the point when an application begins or information is to be perused/composed or any task is to be performed then the information and direction related with the particular activity are moved from a moderate moving stockpiling gadget (attractive gadget-hard plate, optical gadget-CD drive and so forth.) to a quicker gadget.Reserve is additionally a sort of RAM, yet it is Static RAM-SRAM are quicker and costlier then DRAM since it has flip-flops(6 transistor) to store information dissimilar to DRAM which utilizes 1 transistor and capacitor to store information in types of charge.Additionally they need not be invigorated occasionally (in light of bistable locking hardware) not at all like DRAM making it quicker. This quicker gadget is RAM-Random Access Memory).
