Dynamic Random Access Memory Pdf Pdf Dynamic Random Access Memory This document discusses various computer storage devices. it describes floppy disks, optical drives like cds and dvds, external flash drives, hard drives, memory modules, rom, cache memory, and categorizes them as either primary or secondary storage. primary storage includes ram and cache memory, which temporarily hold data for quick processor access. secondary storage consists of longer term. Data storage device hierarchy of storage primary storage random access memory(ram) processor cache & register secondary storage magnetic storage devices hard disk drives (hdds) floppy disk flash memory devices solid state drive (ssd) usb flash drive sd cards optical storage devices compact discs (cd) digital video disk(dvd) blu ray discs (bds).
Memory And Storage Devices Pdf Random Access Memory Computer Data Memory computer memory is the storage space in computer where data is to be processed and instructions required for processing are stored. the memory is divided into large number of small parts called cells. each location or cell has a unique address which varies from zero to memory size minus one. The cache memory, registers, and ram are fast memories and store the data and instructions temporarily during the processing of data and instructions. the secondary memory like magnetic disks and optical disks has large storage capacities and store the data and instructions permanently, but are slow memory devices. A memory is just like a human brain. it is used to store data and instruction. computer memory is the storage space in computer where data is to be processed and instructions required for processing are stored. The devices provide storage that (usually) survives across machine crashes block level (random) access large capacity at low cost relatively slow performance magnetic disk read takes 10 20m processor instructions users typically access via file system, which provides a very different interface and translates to blocks.
