When deciding on   Secondary memory is where programs and data are kept on a long-term basis. Common secondary storage devices are the hard disk and optical disks. The hard disk has enormous storage capacity compared to main memory. The hard disk is usually contained inside the case of a computer. The hard disk is used for long-term storage of programs and ://

    Data Storage from When you need to archive or backup important photos, videos, and files, and you want to ensure it can be retrieved it at a moment’s notice, data storage from can offer a quick solution. From internal to external storage types, you can find it all right ://?node= Get this from a library! A guide to optical storage technology: using CD-ROM, WORM, erasable, digital paper, and other high-density opto-magnetic storage devices. [John A McCormick]

    Secondary storage is storage for noncritical data that will not be frequently accessed. While primary storage typically requires costly, high-performance storage systems, secondary storage systems can function effectively on economical, lower-performing devices that are more appropriate long-term storage. Data that is accessed less frequently can be migrated to secondary storage devices to   One common storage type that you’ll find is optical storage. There are so many different kinds of optical formats for saving information, but they all work basically the same. There are very tiny bumps on these optical devices, and we read these bumps using a laser :// //an-overview-of-storage-devices
