An optical storage device is an electro-mechanical unit that can save and retrieve (write and read) information on a special disc medium using a laser light. Optical drives are designed to work with several types of media: CDs ("compact disc"), DVDs (digital versatile disc" or "digital video disc") and Blu-ray discs.
An optical microscope is what is commonly known as compound microscope.

Secondary storage is?æthe devices for permanent storage and it is not affected if the computer is turned on or not. Secondary storage is?æmostly known as auxiliary storage or external hardware.

DVDs and CDs are both types of optical storage. Optical discs such as DVDs and CDs are certainly more durable than previous storage methods, however, they can still be damaged through everyday use and exposure to the environment.

Summary of secondary storage media. Floppy disk, direct access and removeable.Use Slow Sequential Access Hard disk, high capacity and fastest direct access. Use Store Programs and Data CD-ROM High capacity and removable direct access. Use Entertainment Software, Reference Material Magnetic Tape, High capacity and inexpensive.Use Back-up Programs and Data.
Memory (also known as "RAM", random access memory is "short term", faster access, and more pricey than storage devices. Because it costs more, it is not made to hold as much as storage. Storage devices are slower access, but cheaper and do not wipe out when they lose power. An example of a storage device is your computer's internal hard drive, or a USB thumb drive/USB stick/pen drive.
Secondary memory (or secondary storage) is the slowest and cheapest form of memory.It cannot be processed directly by the CPU. It must first be copied into a primary storage (Also known as a RAM) Secondary memory devices include magnetic disks like Hard Drives and Floppy disks; optical disks such as CDs and CDROMs; and magnetic tapes, which were the first forms of secondary memory... ---------------- Elizabeth Secondary memory (or secondary storage) is the slowest and cheapest form of memory.It cannot be processed directly by the CPU.
