+ Storage device A device capable of storing data. The term usually refers to mass storage devices, such as disk and tape drives.
is a hardware device capable of storing information. There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard disk drive.
+ Storage media are devices that store application and user information. The primary storage media for a computer is usually the internal hard drive. Most internal drives are regular IDE hard drives that come with the computer. A removable drive is another popular storage device that is usually connected by fire wire, USB, or parallel port (e.g. portable Zip drives, Jaz drives, or CD/DVD drives). Newer forms of external storage
include USB thumb drives and camera storage media.
2. Identify the uses of tape, magnetic stripe cards, smart cards, microfilm and microfiche, and enterprise storage.
+Magnetic stripe cards
First used in the early 1960s, magnetic stripe technology, occasionally called "magstripe," remains as an effective form of information storage. While other technologies have come onto the market, magnetic stripe cards are still a cheap, easily implemented system that is seen and used by millions of people every day. The information that is encoded onto the stripe is usually unique to the cardholder and helps to identify that person.
+A smart card, typically a type of chip card, is a plastic card that contains an embedded computer chip–either amemory or microprocessor type–that stores and transacts data. This data is usually associated with either value, information, or both and is stored and processed within the card's chip. The card data is transacted via a reader that is part of a computing system. Systems that are enhanced with smart cards are in use today throughout several key applications, including healthcare, banking, entertainment, and transportation. All applications can benefit from the added features and security that smart cards provide.
+tape drive Tapes have been the cornerstone of corporate backup, disaster recovery, and business continuity strategies for
years. Now, changing backup requirements due to regulations such as Sarbanes-Oxley, new data retention laws, and
the explosion in the amount of data that needs to be backed
up are placing new demands on tape systems.
To deal with these new challenges, companies are moving
to tape automation to reduce human error, save IT staff time,
and speed up data recovery and file restoration. At the same
time, some backup duties are being shifted to disk-based
backup systems allowing companies to take advantage of
the best of both worlds.
+Enterprise storage is a centralized repository for business information that provides common data management and protection, as well as data sharing functions, through connections to numerous (and possibly dissimilar) computer systems. Developed as a solution for the enterprise that deals with heavy workloads of business-critical information, enterprise storage systems should be scalable for workloads of up to 300 gigabytes without relying on excessive cabling or the creation of subsystems. Other important aspects of the enterprise storage system are unlimited connectivity and support for all the different platforms in operation.
3. Describe the various types of flash memory storage: solid state drives, memory cards, USB flash drives, and ExpressCard modules.
4. Differentiate among various types of optical discs: CDs, archive discs and Picture CDs, DVDs, and Blu-ray Discs.
5. Summarize the characteristics of ink-jet printers, photo printers, laser printers, multifunction peripherals, thermal printers, mobile printers, label and postage printers, and plotters and large-format printers
